I also have Forza, but I haven't been able to play it yet. And I may be forgetting a lost title or two.

My girlfriend has her own Viva garden. That's about it for 360. She did play Dead Rising for a couple hours once, but eh.

We play a lot of NES games together. Not so much anything current. 

great idea..if MS were smart then they would do that

If Microsoft had any lick of sense at all the Core would have NEVER even been brought up as an idea... much less released as an actual product. There's no way a harddriveless system has any lasting power whatsoever. It's like when the Dreamcast was released with one thumbstick.

 Just stupid.

Kind of going off on a tangent but... 

I just wish more games would come with a map editing tool.

But, you had to submit it to the company to get approved, or something... to stop the flood of poorly made user maps.

Game and what not is on one disc, editing kit is on another included disc, create - upload to their site, keeps the community thriving. They could update with "best of month" sections and what have you.

It'd be neat. 

Any and all of the RPGs.

Halo 3, even though Halo 2 was terrible inmy opinion.

 Bioshock...

Some other stuff. 

buy it, if she takes it away, call the cops and tell her she STOLE your propertyConManWithGun

This only works if you're not a dependent. Always a fine idea though. 

Guess what? You live once... a $500 choice you make right now is probably going to hold no substantial merit when you're 35. So spend kid!

Work more hours if you have to... when I was sixteen I was working at least 35 hours a week on top of high school and video games and a gap pal, what have you... 

Drive to the store, make the transaction and tell her to chill.

For realz. And then send me some money via Pay-Pal. 

Get the system first. New HDTVs and price cuts are issued all the time.

Waiting a couple months may be a better choice overall.

If you need a game to get you through an extended period of time I'd pick up Oblivion.
