Best-looking 360 games on HD

I would like to know which games look amazing on HDTVs. So far, I've loved the way GeoW2, Bioshock, and Fallout 3 look on HD. Any other games on the 360 that truly look beautiful on HD?

fifa 09 and nba 2k9 look amazing on HD. in fact, when i was playing nba 2k9 my uncle thought it was an actualy bball game on tv lmfao. if i had to pick one game though out of these 2 it has to be 2k9 the graphics on that game are some of the best i have ever seen.

Far cry 2 has some lush scenery.

Street Fighter IV
Assassin's Creed
Bioshock
Project Gotham Racing 4
Resident Evil 5

Mass Effect

gears 2 looks absolutely amazing, so does battle feild bad company.

Gears 2 is the best so far in my opinion.

I would say Dead Space, or Halo 3, given that it's one of the only popular 360 games that is full 1080p compatible.

PGR4 looks really good imo
