So yesterday I bought XBL Gold and it came with 1400 MS Points. I have no idea what to get, I have Geo Wars 2 and I've already played Castle Crashers and Plants vs. Zombies. 
 
What is new and worth buying? Are people still playing Monday Night Combat? I don't really care what it is, I just want it to be worth the points. I have class now, so I'll check this later. Thanks to replies! 

If you have Mass Effect 2 get lair of the shadowbroker :D

Get Shadow Complex! Or Lara Croft! 
 
EDIT: Or Zeno Clash: UE!

That's a really weird number of points.  For that, you can get Scott Pilgrim and Dead Rising Case Zero.  Save the other 200 I guess

Thanks for the suggestions guys. Any more?

If you're a fan of Castlevania I heard the new one is really good.

The only 360 I ever wanted was Shadow Complex...I was willing to buy a new 360 for it. 
 
So you know what game I'd spend it on if I could.

I'll make a top four list: 

1. Castlevania: Symphony of the Night
2. Braid
3. Shadow Complex
4. Metal Slug 3 + Geometry Wars: Retro Evolved (I personally like it a lot more than 2) or Chime

Definately buy Case Zero, it's great value for money.  And let's you have enough point left for another 1200 point game.
 
Good question about monday night combat, it was doing good until the release of Reach, don't know how it's faring now. Would make good use of your gold sub.
 
Other XBLA games that are great: 
* Shadow Complex
* Castlevania SoTN
* Lara Croft
* Limbo 
* Puzzle Quest 2 - if you need a time sink

" Shadow Complex. "

Monday Night Combat is a blast and a half.
Shadow Complex was great and has lots of replay value. 
 
Like HeyLook said, if you've got ME2 pick up Shadow Broker (I'd also say Overlord and Kasumi too - maybe just dump all those points into ME2)

Is there anything new coming that I should hold out for?
