360 owners, how long are these games?

Of the ones I've beaten:

BioShock - 8-10 hours.

Assassin's Creed - Took me about 10 hours.

Lost Odyssey - ~50 hours to do the side quests and everything.

Blue Dragon - Took me 90 hours for 100% completion on achievements. Probably could be beaten in half that, though.
