I'd probably be pleased, actually.
None of the series in my signature require any kind of high-graphical-power to be what they are (arguably WipEout HD Fury, but Pulse was great without HD or 60 fps).
I mean, it was lovely seeing Ratchet in HD and the level of detail when I first played Tools of Destruction was mind blowing. But regardless of that, I played it for the game.
I do see where you're coming from with this point, don't get me wrong, but I can only answer for myself!
