Get a silver account now. Although I originally bought a 360 to play a couple of games which didn't work great on my PC, I've probably put the most time in to XBLA games.

btw for xbox live if you bought a new sealed 360 you get 1 month of gold free if you sign up through your 360 for up to 3 accounts

alan wake definetly 

lost odyessey if you like Jrpg

Fable 2 is great i have 3 but am yet to play it

halo reach

Banjo nuts and bolts

mirrors edge

battlefield bad company 2

nice purchase. hope you enjoy it :)

After reading through these posts, I am most likely to be getting :

- Gears Collection
- Alan Wake
- Gears 3
- Halo : Reach

In the coming year. And maybe even the Lost Odysessy.

Mass Effect 1, no comic-strip can replace this game.

Splinter Cell Conviction is so low priced, it can't be a mistake to buy it.

Bayonatta.

Metro2033, if you like the setting.

Alan Wake has a great atmosphere, but Alan Wakes motions are sometimes antiquated. Nevertheless I enyoed it.

My suggestions

1. Return it and get the 250gb, or alternatively pay $150 for the 250gb hard drive

2. Get Fallout 3 GOTY edition and Fallout New Vegas

3. Halo Reach and/or Black Ops depending which is more your style

4. Wait patiently for Skyrim

Oh and on a side note: when you do make a gamertag, the more x's and i's you put in it mean you're a better gamer. 

Lost Odyssey!

Bayonetta for sure... it's really cheap on Amazon.com

Alan Wake

Final Fantasy XIII

Halo Reach

Gears 1 and 2

Left 4 Dead

Left 4 Dead 2

Kinect :)

You can buy an external hdd too if you want to install your games or download a lot of xbla games.

You have to partition the hdd and the parts you partition for the 360 can't be used with a PC but its still a lot cheaper than buying the Microsoft brand ones. My friend bought a one terabyte external hard drive and partitioned half for his 360 and half for his PC. I'm not sure how he did it but he said its pretty easy.

I think Amazon had a terabyte hdd on sale for 50 dollars today too.
