1. Brawl around 180hours power time (last time I checked was like 170)
2. Metroid Prime 3: Corruption (the save I mostly play had around 13 hours)
3. Wii Sports, not quite sure but def. less than MP3 and more than TP or SMG
4. TP/SMG, both around 3-5hours, haven't played them much yet, want to beat MP3 first.
