I think it is a blast. But if you start with the demo (no training like the retail), then give yourself a couple hours to get used to the controls and what to do in the game. Night one of demo was tough, night 2 was a blast. Night 3 even more fun. Next day, I bought the retail on the way home from work. $29.99 at circuit city this week.
