Game with a good campaign mode

I recently got an Xbox360 and i currently own Halo ODST, Forza 3 (free) and Super Sreet Fighter 4. I wrecked the ODST campaign the day i got it and i even plowed through and returned Gears of War 2. I borrowed a friend's GTA 4 but i didn't find much fun in it.

so currently all i play is Street Fighter online or with my bro, and Halo online and i'm looking for a 360 game, preferrably old and cheap, with a long and engaging campaign mode. Online play or Co-op play would be cool, but just a campaign alone would be great.

any ideas on what to get?

all depends on your tastes - One of my favorite games is Fallout 3 - which Ive put in about 40 hours into, Oblivion is amazing if you can get past the older graphics (my bro is seriously around the 300 hour mark on it), Bioshock is amazing, The Assasins Creed games are awsome (AC2 is much more finely tuned), and Fable 2 is fun but will only take you about 6 - 10 hours.

Gears of War & Gears of War 2.

Fallout 3's campaign is still king in my opinion.

Fallout 3 has a lot to do but the story is not that good and the enemies are not that rich.

Tale of Vesperia is a good story with a nice group of main characters.

The Mass Effect games are nice even if they second is more of a RPG lite.

Lost Odyssey

The Last Remnant (Install it to the HDD and it runs fairly decently)

Timeshift (I'm not kidding)

Dead Rising

Definitly mass effect 1 + 2, that will keep you busy for about 50 - 100 hours combined lol.. If you do all the sides and stuff =) Not to mention the sweet story and gameplay depending on what you have chosen.
