What game should I get for the Xbox 360?

Can someone tell me if I should get a Good game or a list of them? I recently got my Xbox 360 (Around 20 days ago) and I am filling up my collection.

I also have 1800 microsoft points unspended, anyone know what I should get with them? I have planned on maybe getting Castle Crashers or Feeding Frenzy 2, should I get them or wait/get another XBLA game?

I'll tell you my current games, so that you won't recommend any that I already have.

Here they are:

Halo: Reach

Universe at War: Earth Assault

Fable II

Halo Wars

Viva Pinãta

Forza Motorsport 2

Lost Odyssey

Kinect Adventures

Plants VS. Zombies

Super Meat Boy

All free XBLA games available

And the game I randomly won in a lottery, Lips: I *heart* the 80s.

Elder Scrolls IV: Oblivion
