One of the earliest Civilization titles you could play without a tutorial if you've played more recent editions. They really nailed some of the satisfaction that drives that "One more turn..." feeling. Specifically the way your civilization evolves through the improvement of tiles and managing your workers, the visual representation of the wonders around your city. The irony is that despite considerably more complex mechanics, the later games sometimes struggle to get the emergent depth that this game generates through that turn by turn satisfying iteration.

Best turn base 4x game. Civ 4 use world square tile set. Other 4x game mostly use hex tile, don't like too many neighbour tile.
