[quote name='ragingst0rm6']Are the HD versions a significant improvement over the original disc versions?[/QUOTE]
I thought someone would never ask....
Well, I have only played a little of Code Veronica but it is not a very big improvement over the PS2 version. It is the best CVX is going to look on an HD TV, maybe except through VGA on the Dreamcast.
Resident Evil 4 looks VERY NICE. But it is noticable that they used the PS2 version to port it from. There are lighting and shadowing issues that the PS2 version had opposed to the Gamecube version. Also, there are some audio problems. When the ganados yell at you it sounds like they're screaming at you through the speaker at the drive-up window of hell. Other than that, it looks great in HD, and I am enjoying myself playing through it for the billionth time.
