So, the thing is that I will start playing Civ3 again after a long, long time. I've seen that there are a lot of options at CivFanatics, but I wanted to ask you. Any suggestions? Something you played and liked? Any good total conversions?
thanks.
Civ3 has some insanely good mods, though I can only remember two. I believe that the prosperity it's modding community enjoyed was due to the ease in which the map editor could be used. While Civ4 modding required some programming skill (and paid dearly for it), the Civ3 map editor could be used by anyone and consequentially had some inspired results. Civ3 mods consisted of more than just bloated content packages and shoddy, fucked up, half assed scenarios -- at least one of the two listed here was made by some sort of historian dude. So for that reason (amongst others) it's rewarding to choose Civ3 over Civ4 (a game in which modding was entirely composed of the negative elements I listed previously).
Rood and the Dragon
Scenario in which you play as a Saxon country in dark age Britain. It's well designed, as there are several malleable time pressures on you. Firstly the Irish are capable of a cultural victory and secondly there's the coming of the vikings, who pose a major military threat. Between those threats you interact with the other Saxon countries in typical Civ fashion (map painting). The author of this mod was the historian I speak of, so you can trust that the detail put into it's authenticity was high (for a civ game).
Age of Imperialism
Lots of content and really wacky gameplay changes made in order to better mimic the times in which it is set. Word of advice: choose one of the great powers, as the other countries have lacklustre tech trees and the great powers all have unique tech trees. Unfortunately it is rather easy, without any ingenious plot devices like those found in Rood to provide additional challenge. It is your standard map painting experience, an experience which hounds these types of games to no end.
Not to go into too much detail, but in Civ4 you have better combat mechanics(less chance of weird shit happening, like warrior beats battleship), with promotions and other neat stuff, plus the Rock-Paper-Scissors approach is handled much better. You also have religion, which adds a ton of flavor even if it muddles up diplomacy. There's an espionage/corporation system with BtS that adds more complexity to the end game. Culture is handled in a much better way than Civ3. Civ expansion is handled better, and there's a whole new layer to city growth with the health system. The tech tree is expanded and makes more sense, plus it allows some nifty slingshotting through techs for specific strategies. Luxury/health/strategic resources are handled much better than in Civ3(they matter a lot). Finally, Leonard Nimoy. Civ3 was a fine game, but Civ4 pretty much eclipsed it in nearly every way.
Do not listen to this man, he has proletariat tastes.
There are indeed improvements made in Civ4, but they are to do with the UI and overall level of content. Only the UI is meaningful if you intend to play mods, not vanilla. As you say, Civ3 has many notable advantages: modding, which I've listed earlier, but also to do with graphics, as you mentioned, as well as core gameplay mechanics which cannot be modded away. Civ4 can be worthwhile, and indeed it is the only one of the two I play any more, but it has more to do with the ease in which one navigates it's UI that makes it attractive than anything to do with aesthetics, content or gameplay. I would advise playing Civ3 first, lest Civ4 spoil you.
