Centaurs Extractors
In my eyes a very good Corporation, getting science for faster progress and also more hammer to build what you unlock is a good combination. Hammers for sea tiles is an immidiatly, noticable effect without the time delay of generating franchises.
Always useful, no matter which victory condition you go.
Civilized Jewelers
I agree with
@Stalker0 here, this is probably in most circumstances the best Corporation now. The ability to start everlasting GA which boost kinda every aspect of your economy alone is a huge benefit. Additionally and extremely increased GP generation has the potential to generate directly huge amounts of science and culture on top of the boosted yields. You are probably able to create everlasting GA by your own, maybe by GA lenth monopoly, in this case the corporation lose some of its power, but its still extremly powerful.
Firaxite Materials
Science cant be bad, but Firaxite lacks the production versatility of Centaurs, cause the modifier may increase the production for buildings to a degree Centaurs do, but for all other aspects, its worse. Not bad, but in my eyes inferior to Centaurs.
Giorgio Armani
Even after the nerf its a strong corporation, mostly by the fact Stalker0 already has mentioned. Culture is hard to gain, so any extra source is valuable.
Hexxon Refineries
Absolutly useless in my eyes. If I plan a peaceful game and start with a Hexxon monopoly luxury, I immidiatly restart. There are many other ways to come to strategic ressources, buying, CS or simply conquering cities with some by standard units.
Trader Sid's
Money works always. But I also agree, thats not as powerful as Centaurs, cause gold is less valuable than the hammers and science from Centaurs or the overall improvement by Civlized. The high versatility you can use the gold is a big advantage.
TwoKay Foods
Gazebo has already said thats totally normal and obviosly, that growth/food have to decrease in its value in the later stage of the game. While I partially agree with that, its strange that the late game TwoKay Foods only purpose is to generate more of a yield, which gets late in the game more and more useless. Personally I like this Corporation, cause I like big, highly efficient cities. Simply my flavor. Civilizations on food poor terrain like hills, tundra or desert are able to benefit from this corporation, but I agree thats more one of the weaker ones.
Problems:
- Hexxons bonuses are too special. It mainly helps for domination victory, but that late in the game, you already should dominate the world, if you go for a domination victory, and have enough strategics and units. So it doesnt help. If you played peacefully for an other victory condition, Hexxon could give you an advantage to beat a runaway, but keep in mind, that other corporations could give you such an advantage, that you were able to beat that runaway without any war.
- TwoKays Bonus is too low and too much focused on a weak yield. A rise from 3 to 4 food from each franchise should be the minimum. There should be also an additional bonus for offices, which didnt increase food.
Converting food into other yields maybe, or a strong yield increase for specialists AND laborer or yields at citizen birth.
- Some trade route bonuses only increase the yields from external trade routes, but not for internal. This can be a huge disadvantage for Order players or any player which use a big portion of internal trade routes. Every trade route bonus should incrase the yields of its starting city, to stop this disadvantage.
