Elmofongo: Some games deserves HD remakes. My PS2 and Wii are not gonna last long, so I hope Resident Evil Remake, 0, Outbreak 1 and 2 and Final Fantasy XII gets HDfyed.
It would be difficult to make HD versions of those Resident Evil games because they use 2D backgrounds with 3D models, so while it would be easy to make the 3D models (like characters and enemies) scale correctly, all the backgrounds could only be upscaled (similar to what happens when you emulate these games on PC).
Same goes for FF XII on PC, you can set the resolution to 1920x1080, but the 2D backgrounds are stretched.
Unless you mean a complete remake from the ground up, in which case it would be a completely new game.
