The more I play each civ, the more I get the feeling that they are actually all more or less balanced with each other. Some are still better than others dependent on map type or size, or even just random luck of starting position. But I'm really getting the feeling that a lot of play testing went into this. It's more finding the play style that suits each civ best, and that can be hard for some for the less obvious ones.
I'd like to believe that, but given how unfinished the entire product seems, I wouldn't bet on it. Not that I don't think the game is still pretty good, but it just feels like it needs
alot of tweaks.
I do think things aren't as unbalanced as some people are saying, but I do think some civs are clearly stronger than others (which, granted, will probably always be the case).
As an example, take the Aztecs. Their UA and UU aren't very good at all. The UA will maybe get you your first policies 2-3 turns earlier if you commit to warmongering. The UU bonuses aren't that good, as jungle battles aren't too common, and the healing isn't much. Granted, the UB is fantastic, but can that alone put the Aztecs on the level of a civ like say, Greece or France?
Greece has two very powerful UUs that come at around the same age and probably one of the best UAs in the game, and France has two solid frontline UUs and a UA that is strictly better than Monty's. Now I think Suleiman's UA is by far the worst in the game, but at least he has 2 very good UUs that come around the same age. The likes of Monty and Harun are just clearly weaker in general IMO.
I do agree that they're well
designed though. Different civs are extremely powerful in different ages, and you really feel that: being Alexander's neighbor in the Classical Age is terrifying.
On that note, I'm also going to say that I think China is stronger than you think. The Paper Makers are a very good UB (one of the best around, IMO), as libraries are generally built everywhere, and the fact that they're effectively maintenance free (and in fact add to your gold count) mean your can spam them without worrying about cash. A decent sized empire powered by Paper Makers mean you tech faster and have more cash, and teching faster gets you to Cho-ku-no quicker. With uber-GGs, those guys are beastly.
