360
im not a fanboy at all i just think you get a better value with the 360.
1. The 360 pretty much has all the games the ps3 does, plus some really nice exclusives.
2. X-box live is the best online community of a console so far. Its very strong amd user priendly.
3. The 360 is cheaper, and there is really no difference at all in graphic quality in the systems. Pretty much one has darker grahics, and the other has lighter graphics.
4. Blu-Ray player on ps3 isnt that great, and isnt really used well yet. Blu-ray is new, DVD will be the standard for a while.
5. More people have 360's therefore you are most likely to able to play with a friend.
6. GTA extra content is 360 exlusive so far. THis is extra content that will expand the game that you can get off the marketplace.
7. Forza motorsports.
PS:
Im going to school to design games, and x-box has a feature where you can make games using torque-X, and you can upload your games into xbox live arcade for others to buy and play. This is the best thing you can do if you are a game designer starting out.
