I'm playing computer games for about as long as I can remember! I begun with arcade games(at stores - needless to say, that I have spent fortunes on arcade games) at the age of 11(I could fill whole pages, only writing the names of the games that I've played), have owned consoles, and own a PC(and never looked back again to arcades or consoles) since 4 years. I'm on the 21-30 age group.
What I love in Civ, is the way you need to plan for every single action/decision you take: I just love it!(The Turn-Based system gives you the time to plan everything). It is like chess. That's what made me like a "God" when I played arcade games, way back in those glorious days: other people came close to see me playing, but they mostly failed to realise that you first need to understand how the AI(in every game) behaves and what it'll do when you make a specific action; if you know how the AI will correspond, the game is already won!
