all we need is HD games w/ FM extras and cutscenes. All available for current generation systems.
I get wat your saying for coded, and days. But simply all they need to do is to improve the graphics to PS2 standards, or HD if we get lucky, and add more voiced cutscenes instead of speech bubbles.
as for CoM, it is already remade for PS2, but it couldnt hurt to remake it again to HD graphics. also they should tweck the gameplay of CoM a little bit more so It can be more exciting.
