Mass Effect 2 and Lost Odyssey are my favorites, but Star Ocean is pretty good also.

Tales of Vesperia
Final Fantasy XIII (Its coming out in 7 days)
Mass Effect 1 (haven't played 2 yet but I've heard its even better then the 1 one)

No Enternal Sonata unless you want to be bored to death, just get Tales of Vesperia for 20$.

I mostly agree with this, but switch 1 & 2 and switch 7 & 8.

ME 1+2 are MUST plays (especially 2, but to fully appreciate/understand it, you have to play the first).

In my opinion on 360 Mass Effect 1 and 2, I like #2 the best bot both are superb, I say ME because it Takes the best elements from both RPG and 3rd person shooter in one game with a great great story, ME2 shooter wise plays just like Gears of War 2, but with much better weapons and powers, Mass Effect 2 is both Legendary and Epic, my favorite game on 360 hands down, and I am a hardcore shooter and Adventure fan.

1. Fallout 3 (the best open world WRPG since Morrowind, tons of fun but much better on PC)
Tie 2. Mass Effect 1&2 (WRPG with excellent story telling and fun gameplay similar to KOTOR)
Tie 2. Dragon Age Origins (excellent WRPG similar to classics like Baldurs Gate and NWN)
3. Lost Odyssey (my vote for best JRPG this gen so far)
4. Borderlands (greatly underrated with solid gameplay but no real story)
5. The Elder Scrolls Oblivion (greatly overrated but still a good game with a weak story)
6. Fable 2 (overrated on release but still a good game that provides an interesting change of pace from the norm)

Thanks for replies! Looks like most ppl are saying Mass Effect, I guess I'll go w that!

WTF? dont listen to these idiots.

Mass effect, oblivion, and fallouts are great; however, they are all multiplatforms. You could play them on pc.

If you play those games then what is the point of you borrowing your friend's 360?

Play something that is exclusive to the 360 or console(if you dont own a ps3) for godsake.
