Well, if your a Shumps fan i'm sure you have played Ikaruga.

But in case you no longer have the game its available on xbox live arcade http://www.youtube.com/watch?v=OMT1b2R6zcY

gears 2, star ocean, mass effect, fallout 3,dead space, ninja gaiden 2

I got you my man. Congrats n purchasing an Xbox 360. Heres a few games i reccomend.

Gears Of War 2
Forza Motorsport 3
Halo 3 ODST or Halo 3 since you wont jump on the online
Fable 2

I recommend at least 10 copies of Earth Defense Force 2017.

Stop over-exagerating badger.......the disk scratching problem with the 360 isnt that bad

You can find Crackdown very cheap...and its worth it so make sure you pick that up..

LO and Gears are great choices...

I also recommend Forza 3 & Fable 2...

L4D 1 and 2 is good it makes me wish it was on ps3 also dead rising but u already have it on there

if u like gta4 the dlc for the box is even better u can get them in disk format now too

Episodes from Liberty City (you don't need GTA IV to play it)
Condemned
Blue Dragon
Halo 3/Halo 3 ODST (for splitscreen co-op needs)

W.E.L.C.O.M.E To The Light!!!! Get L4D2!!!

Left 4 Dead 1 & 2 are simply fantastic, OP, if you dont plan on getting live take advantage of your free 1 month trail, then when it runs out make 2 more accounts and get a total of 3 free months and play these daimond games online, you'll love 'em.

Ultibankai.................................. Start that Mortal Kombat petiton, there hasn't been a good MK since UMK3
