I've always wanted a definitive collection of the average length it takes to beat particular games, why? Well as a working man, I haven't much time to play anymore, and I'd like to know before starting Prince Of Persia: Warrior Within (or any other game) just how long it takes to complete, on average.
If the game is an RPG or has multiple paths, extra levels, etc. Post 2 lengths. For example, in an RPG, if you go from start to finish, it may take 30 hours to complete, or it may take 100 if you go through all the side quests.
So post the CURRENT GEN CONSOLE (PS2, Xbox, NGC) game lengths you know of. And especially some short ones!
To start off, here's some that I can remember. If you feel that I, or someone else is wrong, please add your opinion:
Gamecube
Donkey Kong Jungle Beat - 3-4 Hours / 5-6 with bonus levels
Luigi's Mansion - 8-12 Hours
Resident Evil 4 - 18-22 Hours
Sonic Heroes - 10-15 Hours / Over 4 times that beating it with all characters and unlocking Super Sonic
Wario Ware Inc. Mega Party Game$ - 2-3 Hours / Unlimited if you plan to beat scores and unlock all games
Playstation 2
Gungrave - 4-6 Hours
Katamari Damacy - 8-12 Hours
