Does the AI know how to sail?

    I searched the forums first to see if anyone else has posted anything about this yet, but I didn't find anything. But it might just the games I've played.... ;)

    I've played a few games so far a prince/standard size/continents map. One thing I've noticed is that the AI doesn't seem to explore the world at all. They basically stay on their continent (or jump to a small island nearby). I've never met another civilzation by them sending a boat across the ocean. I always find them.

    As a test, I stayed on my continent the whole game and then starting sailing around after 1950 or so. I found small islands with barbarians still on them, and also met the rest of the (surviving) civs and city-states in the game.

    Has anyone else found the AI civs to be rather weak at exploring the world via the oceans? :confused:

    For me, the AI's in any Civ are not gifted with boats.

    Now you mention it, no. I've not seen any AI embarked units. At all.

    I have seen Naval Combat units though. They do seem to like sending them round the world to bombard Barbarian Encampments. I've seen this a few times.

    Oh god, it's Empire Total War all over again...... surely not......

    If you want hot naval action, i would recomend playing on the Small Continents mapscript (its in the advanced options) its basicaly a middle ground between achepegio and continents. i play with high sea level and lots of civs, there is always alot of action both on land and sea.

    the AI isn't GREAT at naval maneuvers, they don't protect thier transports well enough, but they DO use boats quite a bit. if you hold a choke point on one of the continents, they will embark and sail around and attack elsewhere. they also invade other continents with some frequency.

    sometimes i think i somehow got a different game than everyone else... AI in my games always plays reasonably well. well enough to be a challenge anyways. If only i could get a start away from Siam and his stupid elephants...

    I've seen embarked units. Rarely.

    My theory is that the broken pathfinding that basically ignores water and/or treats it as one tile per turn terrain affects the AI much more than it affects a human player, who may be smart enough to realize that the shortest path is actually not a full circle around that lake there...

    I've blocked land brigdes with a single warrior and it took the AI a loooong time until it embarked the first units and moved them across.

    I tried to 'power game' the English UA by going max naval discipline and building the Lighthouse, but it turns out command of the sea isn't nearly as important as it might be if the AI knew how to use it.

    Sure it's handy being able to move a caravel 1/5 way across the map in a single turn and bombard pirates / ******** unescorted enemy transports but I feel like the only player playing the naval game at all.

    I often see AI embarked units (sometimes even when it's not really needed). Much more often, then combat naval units.

    In previous game I've seen pretty nice invasion force from Siam for Romans. It was about 5 or 6 embarked land units, and 2 caravells and 1 frigate as escort. Moreover - both siam and romans were on the same continent, but water path was really the simplest one, and AI was absolutely right there.

    So, AI "know how to sail". But how good he at it I can't justify yet.

    As far as land warfare, the AI in my games seems decent as well. At the very least the AI seems to know the importance of having his artillery behind the front lines. :lol:

    In my first game I saw the Japanese moving a large invasion force across the ocean to attack Napoleon. Several destroyers and a few riflemen.

    That is a something I didn't consider: the personalities of the AI opponents I've been playing against. Most of them have non-warlike personalities it seems.

    I guess I won't be seeing a Gandhi invasion force anytime soon. :crazyeye:

    The naval AI is badly messed up. Here is a good example: I cleared out my continent quickly, then went on the tedious march to a culture win. I had 4 AI city-states. The other continent got taken over by one AI mostly (the other survived in a corner with very limited access)...and the big AI nation ate a bunch of city-states, leading the rest to declare war on him.

    A contintent-spanning superpower vs. a handful of isolated single city-states on the coasts. What could be easier? Well...I then watched as the AI sent a handful of boats to aimlessly shell the cities, destroying sea resources occasionally. A couple of times a unit or two got landed and squashed, even though there were a lot of other units parked in boats on the other (nearby) shore). Centuries of endless war, and the AI couldn't even take out a single city even with overwhelming superiority. I occasionally would gift units to some of the city-states to see what they'd do with them - the answer, basically, was that they would just get them killed in the same way that the invader units died. We're talking MOO3 level AI here...

    I spent most of the game with 2 land military units once I realized that the hordes would never arrive. Happened with Persia, Aztecs, and Japan on the other continent (different games), so I don't think it's the AI personalities.

    Hmm...so if you can take over the continent, or control it, then you're pretty much safe the rest of the game from any invasions? Very interesting.

    I'll have to test that when I get out of work today. Having a job is slowing down my Civ V "research". :king:

    Earth map, I control Americas as Songhai, Lizzy has conquered whole eurasia and half of africa (lower half is Montys).
    She keeps sending her stupid UUs to attack my coastal cities... VERY annoying, but not broken. When I finally decided to take them down with Ironships (the ship that can't enter ocean but has cannons), I see her embarked riflemens approaching brazil area. I manage to take them down (4 of them) before they get to my undefended south-america.
    Broken? I don't think so.
    Difficulty was Prince, if anyone cares.

    I've seen proper large invasions on King. Embarked units hitting simultaneously from multiple angles, boats defending them and then bombarding the land, the works.

    This is not the case in my experience. you are more safe than if you share a border with Napoleon on pangea, but the AI will still invade occasionaly if they find a reason. most likely they see consolidating power on thier own continent a more pressing concern.

    in my past game i was alone on a small continent/large island, playing as China. Siam asked me to go to war on the neighboring continent with Hiawatha, so i did thinking i could gain a foothold there.

    Siam attacked over land from the north while i invaded over seas from the south. While i was bogged down fighting mohawks in forests, Siam rolled through the open plains to the north with his elephants.

    before too long, Hiawatha was gone, i had taken two cities and Siam had become a major world power. a turn after defeating Hiawatha, Siam declared on me. he took my new cities in a few turns, brushing aside my battered forces. while i readied my defenses back home, he embarked a good dozen of those damned elephants backed by cannons and riflemen. difficulty was on 6 (emperor?) and he had a tech level on me.

    the invasion was well executed, and though i put up a valiant defense, it wasn't enough. i didn;t succeed, and so, i ran the risk of failure. :(

    I agree the ocean helps, especially early on, but after a while, it is essentially a gigantic open plain where your land units need the same kind of escort as settlers do.

    Those elephants are brutal... I didn't bother with catapults in the game I used them!

    I've never in any of my games seen an AI attack cross-continent by sea.
    never.

    only tiny (and mostly stupid) embarkations to encircle a sea-side city of mine.
    Which is of course problematic because the city kills any unit that embarks, thus surviving indefinitely against great odds.

    on my last game with india on king on a pangea map.

    I went for a cultural victory but after a while the ai got to powerfull and i had to attack what was funny was that there was a big lake in middle of the pangea and the AI had around 9 destroyers inside kkkk

    if that was outside i would have being destroyed since i had very little oil.

    but i wish the ai was smarter about the sea warfare i really enjoy the new combat and would love big water battles
