Rainbird on 05 December 2008
Best graphically? I have no idea, I can't even say for sure which one of those it wouldn't be.
Best game over all? All but GT5 (or rather, I have no idea), not that it will be bad, but of all genres up there, racing is the one I get the least entertainment from.
I think Heavy Rain will in fact be something completely new, and a game that will go unmatched in terms of story telling for some time. Perhaps only until Quantic Dream makes their next game.
You said it best yourself, only time will tell
