What's worth buying for 4200 MS points on 360?

[ws6chth]

I have never really bought DLC before but I am thinking of buying with 4200 points and buying on XBL:
GOW2 All fronts- 1600
Duke Nukem 3D- 800
Braid- 1200

Are these good buy's? Or am I better of buying something else. I dont have any of the other map packs. Also what would be a good use of the remaining 400 points?

NOTE:
I will not buy GTA 4: Lost and the Damned, Fallout 3 DLC or Halo 3 ODST since they will be released as retail soon (on disc).

I own (On 360):
Oblivion
GOW
GOW2
COD4
TOB
Far cry 2
Fallout 3
GH3
GTA4
SR2
Fable 2
Dead rising
Bioshock
GRAW
PDZ
Crackdown
Burnout
PGR3
Halo 3
MD collection
RB
TOV
RE5
SO4
Ghostbusters

thanks.

Castle Crasher, and Symphony of the Night should be a good contender. I've heard good things about Splosion Man as well.

Oh and Battlefield 1943 is awesome as well.

I have Duke Nukem and while it's fun, the game is pretty dated now. Unless you really liked it years ago and need to play it again then you should probably stay away.
