So I remember many years ago that my older brother bought a copy of Civilization: Call To Power. We both loved that game and dedicated many hours to the joy of conquering the Earth and building all the city upgrades we could. The crazy thing about it was that if you sat down for a quick game, you would look up and realize that 5 hours or more had passed! I can't remember another game that I played that just sucked me in so much that the rest of the world slipped away. Has anyone else had this sort of experience with a game?
