Launch titles are always the previous gen's forgotten shite with a tiny bit of polish.
Goldeneye 007 Reloaded
Metal Gear Solid HD
Resident Evil 4 HD
Some other classics recently launched in barely-passable HD that I can't be bothered to Google.
may have been a launch title but the others certainly weren't.
HD remakes are a different thing.
The 360 launch titles are as follows
Amped 3 (2K Sports)
Call of Duty 2 (Activision)
Condemned: Criminal Origins (SEGA)
FIFA Soccer 06 Road to 2006 FIFA World Cup (Electronic Arts)
Kameo: Elements of Power (Microsoft)
Madden NFL 06 (Electronic Arts)
NBA 2K6 (2K Sports)
NBA LIVE 06 (Electronic Arts)
Need for Speed Most Wanted (Electronic Arts)
NHL 2K6 (2K Sports)
Perfect Dark Zero (Microsoft)
Peter Jackson's King Kong: The Official Game of the Movie (Ubisoft)
Project Gotham Racing 3 (Microsoft)
Quake 4 (id Software and Activision)
Ridge Racer 6 (Namco)
Tiger Woods PGA TOUR 06 (Electronic Arts)
Tony Hawk's American Wasteland (Activision)
Not many gems there.. In fact apart from CoD
which went on to spawn MW
I don't think any of those franchises have been missed or in fact that any of those games would feature in anyones top ten 360 games.
