A session report, played on revision 817. Byzantine on Emperor. (Details: First time on emperor, but I knew about all spawns from playing on monarch. No reloading.)
The early war was a brutal wakeup call for the Byzantine Empire. As in history, a strong expedition was sent west to conquer Carthage and Italy (four swordsmen on the prepared fleet).
Constantinople dedicated itself to growth and culture, while the rest of the provices went all out defensive. From the first year, it was clear that the barbarians would be brutal. The countryside in northern Greece and Anatolia was repeatedly pillaged, and only the presence of promoted archers behind walls provided relief.
By the year 600, Sassanids and Slavs were hitting their fronts hard respectively. Still, a few more soldiers managed to be siphoned off to Italy without endangering the defenses.
In 636, the Arabs spawn. The plague has hit hard, and several strong defenders have fallen. Barbarians captured Hadrianopolis, just as it got hit. As in real history around this time, the walls of Constantinople proves the saving grace of the Empire, as endless hordes falls against them.
Though the Arabs flipped several cities, they had been evacuated beforehand. After that, they were content to send but token forces to Egypt and were willingy to make peace for paltry sums (10-30 gold).
By 720, the Lombards had proven too strong (together with the corrupt Empire officials ordering some defenders off to Rhodes) and Florentia fell.
In 748: Arabia declared war again. Their aggression were as weak as in the previous war, and we eventually made peace with the loss of only a few fishing boats for the Byzantines. While they ask for Antioch, they are perfectly willing to settle for 10 gold.
In 764, barbarians press through, ignoring Rome. My belief that Neapolis would be safe proved wrong.
Beleaguered Byzantine defenders try their best, but in 772 Florentia falls again. Italy is crowded with barbarians.
Around 880, things started to calm down. Bulgaria and Arabia absorbs the barbarians (after a few futile attacks from Konniks against me). However, even as my vassal, Bulgaria can't stand against the barbarians and fall.
In 921, the Empire is holding its own against barbarians. First contact with France. They live, but are weak.
However, compared to them, Kiev are miserable. While desperately seeking the Empire's assistance, they quickly fall to barbarians.
Throughout these times, and especially after the fall of Kiev, the barbarian pressure in the former slavic area has increased. Anatolia is fortified against a rumored Seljuk threat and easily dispatches any barbarians coming. North Africa is entirely calm and busy expanding its Byzantine holdings along the coast. A decision was made to found a city in modern Moldova as a Bulwark, to prevent the incoming hordes from pillaging. However, that proved to be a critical policy mistake. Not once, not twice but thrice well-funded expeditions (at least five units, settler, missionary) were killed before they even managed to settle a city, much less build the critically needed city wall. Furthermore, these expeditions weakened the defenses behind the lines, exposing the Bulgarian cities, eventually leading to their destruction.
Hungary offer themselves as vassal in 1041. They are hard-pressed by barbarians, but manage to survive.
1074: The last of the ill-fated expeditions are sent. Notice the newly resettled Bulgarian cities.
1086: Bulgaria respawns, and the Seljuks arrive. Their first wave looks scary, and several workers have to be sacrificed as bait in order to save the cities. But after the initial wave, their attacks quickly petered out, leaving Anatolia much more safe than expected. As always, the true problems lay in the Balkans.
1095: Bulgaria destroyed by barbarians, poor Ivan only got nine years.
By the mid-12th century, the tech rate is abysmal. The Empire has got way too many cities, and no one wants to trade, as exmplified by the Pope here:
In 1239, the first Keshiks arrive. This would be bloody.
Tunisia declared indepedence in 1242. The safest provinces of the Empire was no more.
The officials had thought Egypt was safe since the Arab were still alive at Saladin respawn, but alas, they declared independence 1263. Our beautiful chain of 11 cities in north Africa was now all gone. The remaining garrisons actually managed to capture Cairo in a futile attack of revenge, but it was handed back to secure peace.
1272: Suprisingly enough, the biggest threat to the Empire from the Mongols came not in Anatolia but in the Balkans.
The second UHV was secured in 1284. Anatolia was in beautiful shape, but Greece/Balkan lay in tatters, as the high-producing Thessalonica fell.
1317: While it can be bonus for the player that the cities lost to barbarians revolt and rejoin you so very often, they are extremely quickly dispatched when you don't have castles.
1326: The citizens and emperor alike praised God for the walls of Constantinople: Two crossbowmens, one arbalastier and one cataphract managed to kill 11 Keshiks, without loss, in a single turn
1350: The revolts and rejoining are getting somewhat out of hand, nearly all of Greece rejoins the Empire (with devastated countryside and without infrastructure) before the reconquista force is even assembled.
1359: With Thessalonica and Athens still in Mongol hands, the Ottomans arrive. The flipping cities are handed over to avoid having massive unit conversions.
1374: Black death, and a fresh wave of mongols. Thankfully, the defenders from Anatolia weren't removed (~5 promoted crossbowmens in each city, behind castles).
1374-1450: Continous warface against Ottomans and Mongols. On average, 5-10 keshiks were killed per turn. In 1431 Damieta revolts and joins the Empire, even though we had neither owned, nor attacked it. A few turns after getting it for free, a "Byzantine" revolt occurs there. Nicaea is recaptured from the Ottomans after bloody fighting, but nothing else. The saved money is more than enough for victory!
Impressions:
It was really, really fun!
The game consisted of more or less continous defense - from the initial Slavs and Sassanids, through Arabs and Bulgarians, horse archers in the east (Pechnegs, Cumans, Magyars...), Seljuks, Mongols and finally Ottomans. Somewhat ironic, the Arabs and Bulgarians, together with the Seljuks, were absolutely the easiest to deal with. The early horse archers and the Mongols in the Balkans were the hardest, probably because I was less prepared for them than the threats in the Balkans.
The first UHV required you to dedicate Constantinople to culture. This felt historical, and provided a nice contrast to the otherwise warfare heavy play. It also emphasized the historical role of Constantinople. The second required an assault on the spawned barbarian city with longbows, which was vert costly (especially since I made an unsuccecssful assault with a very lager foce). The third was trivial, as the tech rate was so slow in the end running several hundred gold in surplus hardly made a difference for tech.
Before the revolt, North Africa was my safe haven. Perhaps a few barbarians could be added there in the form of bedouins? My tech rate was abysmal. In the end, I had cataphracts, but nearly all the game was spent with crossbowmens, swordsmen and spearmen as the primary weapon (and before crossbowmen just archers). They sufficed, and the key was to get city walls, and later castles up and running everywhere. Thankfully, Egypt was easy to keep with the stone. Once the defenses unraveled, most notably in the Balkans and Greece it was nearly impossible to keep it together as I lacked the infrastructure. Similarly, my idea to build a city in Moldova to contain barbarians coming into the Balkans failed as I couldn't get even a large expedition far out beyond the cities. The empire was in collapse the whole time, but Byzantine powers kept it safe. I guess other nations will be harder, due to stability hit from barbarian pillage.
Balance points: The amount of barbarians were adequate for a fun game on emperor - do not decrease. If possible, have the Seljuks spawn more stacks during a longer period, they were pitifully few.
I would like the Arabs and Bulgaria to spawn with more units to be more of a threat. Though I guess it would cripple an ai Byzantine?
An idea to consider would perhaps be to add something like 25% bonus against barbarians for all ai civs on emperor difficulty?
I think the cities lost to barbarians revolted and rejoined too often.
Many times, the notification said new mercenaries were available for hire, even though there weren't.
Italy is very nice to have as a Byzantine, to get Condottiere mercenaries.
Some final screens:
All in all, a hectic game that managed to keep it fun the whole match. I can wholeheartedly recommend it!
