This is actually a difficult question to answer. I know I never kept track of the time I spent on the game. I would play a couple hours here, a few hours there and really don't remember how long it was from start to finish.
It was long enough that I felt I really had gotten my money's worth, it was short enough that I replayed the game. I like W&W particularly because it isn't *too* large a world (as the M&M games have become). I'm still playing this game!
