I still play all the civs. Each one provides me with a diffrent style of game while maintaining the core of series.
I still play Civ 2 because:
I really like the maps it comes up with, a good mix of small and large landmasses
I think ZoC adds a good element to combat that I miss in III and IV
As does losing whole stacks of Units in one battle if not careful I can live without this in III and IV bit I don't mind it in II
I think II got the corruption and waste levels right, III was way OTT, but I'm finding I like the soultion in IV, I still Play III but when I want to play a vast empire I go for II most of the time.
I like how trade and spys work in II, I don't mind the changes in III and IV but I sometimes wish they had found a use for caravans.
The advisers, I can't stress this enough "Give me more soldiers so they may sheth their swords in the beating hearts of your enemy" never gets old, even after 11 or so years of hearing it and who doesn't like to be told "all the world marvels at our superior intelect"
All the scenerios/variants with the expantions are just great, along with the user mods (thanks guys BTW)
Teraforming 'nuff said
in fact I agree with all the Civ II players so far. I'm still learning IV and I think it will see more play for me than III esp when BTS arrives in the post (that does look great) but I can't see that I will ever stop playing II, ever. Mind you I don't think I'll ever stop playing I , III or IV either its just some see more play than others.
I recommend picking up The Civilization Chronicles if you can get it at a good price, it has all games and expantions except Civ IV which it just has the vanilla game for, I even play Civ I now but for me thats just nostaliga, although its still a great game
