What games feel next-gen to you?

For me its been these games.

Gears of War - Amazingly intense campaign, co-op at its best

Oblivion - Story was nothing special but with so much to do who needs it

Rainbow Six Vegas - This games is what a next-gen FPS should be

Forza Motorsport 2 - The best racing sim I've ever played

GOW. very powerful graphics

FM2. very reality and lot of options to tune ur car

Crackdown... complete lack of loading times and the graphics look awesome when there in motion.

Oblivion, seeing the detail when fighting in first person.

The Darkness- Awesome story, great twist on the FPS genre, keeps you compelled from start to finish

R6V- awesome online play, awesome graphics, intuitive control system

Crackdown- Intense replayability, possibly best online game to date on 360, just a fun game full stop
