Castle Crashers is perhaps something to look into. The XBLA Lara Croft game is supposed to be pretty good, although I haven't downloaded it myself yet.
For some old school shooting then DOOM and Duke Nukem 3D are fine games.
Pac-Man Championship Edition is one of my favourites.
Best thing to do is to download a trial version and see how you get on with it. That way it is a case of try before you buy and you don't waste those points!

That links to some of them but I'm pretty sure there are more if you go to the section whilst on your 360.
