Yes, another graphical debate thread :P
I've seen many of these around in the past, often discussion what the best looking games of each generation were (Star Wars Rogue Squadron 3 on GC for the seventh gen if you ask Lilbroex, I believe; a lot of people seem to be saying The Last of Us for the current gen).
But I'm interested to hear which game you think pushed the hardware it was running on the most. Invariably this means I'm asking for the best looking game on each system, but which title do you think got the absolute most out of the console it was designed for?
It doesn't have to be in terms of graphics either, although I thought that was the easiest thing to discuss. If there was a game which you think achieved a particular sense of scale which was far beyond anything else running on the console at the time, I'd be interested in hearing about that too!
Normally I'd pick a game to add to the OP to open up discussion, but I'm actually at a loss. I don't really know what titles push hardware, because most games look more than playable enough to me.
