15. Sid Meier’s Civilization IV (PC – 2005)
I should not be allowed to play this game. Once I start a session, I will not be able to stop until 7-8 hours later, when that round is over. I am not particularly good at this game, but I find it extremely addicting to play, and challenges the player in a great way. It is of course satisfying to destroy your opponents in a war, but I actually find it more satisfying to try and keep the diplomatic relations stable and gaining power in more pragmatic means. This is my favorite strategy game.
