Dragon Age & Half-Life 2: Episode 1.
Also with Dragon Age if you haven't already bought the PC version, I actually recommend the 360 version. They have different battle systems, on PC its point-and-click oldschool style, on 360 its a bit more like Mass Effect in how you fight and tell your AI buddies what to do, it's a lot faster on 360.
One friend of mine hated it on PC and loved the 360 version, another liked the PC version, personally I played it on 360 loved it.
