We are definately getting closer and closer to having all the features of Civ4. Yes, I believe Civ5 is better, but still missing a few things from Civ4:
1) Health (and health disasters like the black plague hitting a city or area)
2) Events (like the mentioned plague)
3) Slavery (would fit nicely with the World Congress as you could vote against it): Could work simular to Civ4, but also have a diplomatic impact, espcially the further into the game you come. Bad impact for civs of order but most bad impact on civs with freedom. Besides rushing buildings and units, you should also be able to just increase your production for each turn - think black people in the states before they were liberated.
4) More leaders for each civ: Based on a few observations I think they originally planned to include more leaders for each civ, but many opinions have changed in the last 3 years
I really hope we will see this soon as I would like some great leaders from civs I know rather than civs I don't know. Each leader could have their own UU or UB, while the other UU or UB coule be civ-specific. You could even have a unique UA for each leader. Take England:
George IV (i think): Longbowmen
Elizabeth: Don't know, but there should be something to pick for her
Victoria: Man-o-war
Churchill: Spitfire
Their unique unit for the civ could for instance be the red coats (if they really were famous).
This could really be great if you ask me!
I've often thought about new features for an expansion pack, and here are a few ideas
1) Highway: Connect cities and gain a gold bonus (simular to railroad gives you production). Could be further improved if the city had a parking house (can't remember if that has been available before, but I guess it was Civ2 or Civ3 that allowed highway as a city improvement.
2) Fusion plant (no risk of breakdown compared to a fission plant)
3) Electric grid: My bess idea...
Coal power: One city / Pollution / Consumes coal
Oil refinerary: One city / Pollution / Consumes oil
Solar plant: One city / Needs desert
Wind mills: One city / Needs hills or water / Expensive (for instance)
Fission plant: Three cities / Needs water / Risc of breakdown / Consumes uranium
Fusion plant: Three cities
Now, if you were to build a fission or fusion plant, you could connect the cities via an electric grid. This way you could have only one plant for every three city. If you build more you would have surplus and could sell it to other civs (through the new trading system) or you could have it as a backup in case someone were to cut your grid.
4) Unions / federations: Simular to the World Congress we get, but now I'm pretty sure we'll never get them for Civ5. You should be able to build a national wonder that gives you the possibility to create an union / federation. From an option menu you could set up a handful of laws:
a) Leader selection (choose "Leader for lifetime" or "Elected leader" where you can select to vote every 5, 10, 20 or 50 turn)
b) New members selection (choose "Leader decides", "50% vote", "Anomious decision" or "Creator decides")
c) Policy selection (same as above)
d) Resolution selection (go to war, force peace among members, etc. - choose between the above mentioned)
e) Members leave ("Ignoring decision", "Leader decides", "50% vote", "Anomious decision" or "Creator decides")
f) Ignoring decision ("Kicked out of union" or "Not possible")
You could come up with more ideas, but the thing is that you can create any union you would like. Make an "European Union" with open borders and trade bonuses or create a "Soviet Union" with common policies based on the order policy for instance. After creating your union / federation you could ask others to join, they could ask you to become a candidate (and be full member through the given rules of member selection, or you could force other civs into your union (attack and settle the war with a demand for a union).
5) Independence: Possibility for your cities to revolt when angry. This would create partisans and for every turn there should be a small risk of they declearing independence. If they do so, a new Civ appears in the game, and they start up with anything from 1 to all but one of your cities (depending on the extention of the unhappiness). Think america - England exploited them and they revolted and finally decleared independence. Independence is an important thing in the world, and so it should be in Civilization 5. If you were at war, your enemy would be likely to ally the newly created civilization (think America and France again), and you could try and take it back or settle for peace and get the extra happiness.
Furthermore, civilizations not able to leave an union could declear independence from you (think Balticum in the Soviet Union)
6) Create colonies: Possible with the new african scenario. Create miniture cities to achieve slaves or increase trade. Possibility to enter a colonial war with another civ where cities are "immune".
Then you certainly will be upset when culture flipping gives away your only source of oil to the enemy. Have fun in your upcoming wars my friend. May they be plentiful.
Anyway I am just joking it struck me funny is all. I hate culture flipping and would not care to lose my wonder to an earthquake, but I would grumble a bit and live with it.
Has anyone mentioned anything about culture flipping?
I suggest to PLEASE replace the awful voice dubbing in Spanish Isabella has in the game. No emotions, dull and boring! Spaniards are known to put a lot of passion when speaking, she sounds so awful!
... and Harald Bluetooth! He just sounds too much like a 35 year old desk clerk playing role playing games in the woods on his sundays
Be glad you aren't danish and have to listen to that..
