I bought some points and I would like to hear some recommendations for what to buy.

I am pretty sure that I will get DAO: awakening. Are those other DAO addons worth to get? Any other good addons for games? I own a lot of games so any recommendation is welcome. Maybe even some XBLA games, too.

Get Banjo-Kazooie if you can, and download mainly add ons. 

Nuts&bolts?

The original game on XBLA, it should be 1200 MS points and there's also the sequel Banjo-Tooie.

Oh.. no. :P That is way too much for an old game. Platformers aren't my thing either.

Have you considered Shadow Complex, best game on XBLA by some distance for me

Somehow that reminds me of some old snes game, propably metroid. Is it similar or is it just the screenshots?

Shadow Complex is great, and Castle Crashers is hands down my favorite.  Others titles to consider are Braid, Splosion Man, Portal: Still Alive, Geometry Wars 2, Limbo...

Yeah it is pretty similar to metroid if not even more awesome. Definately my favourite xbox live arcade game.

Dude it's the summer of arcade.

Hydro Thunder!

Limbo!

The new Castlevania!
