If we don't draw a line then anything can count. From FMV games to pre-rendered cutscenes.
Well, yes, that's rather the point! You need to draw a line, because 'most graphically impressive game' is going to mean different things to different people.
If the word is 'impressive', then it's really not Dragons Lair. It might have been the prettiest for a long time, but I'd imagine that most people stopped being impressed when they realiserad it was basically just playing a video.
Well, yes, that's another fair point. If the word is 'impressive'... should we also take the hardware it's running on into account? Because, after all, there's a
reason people throw around this line:
Uh Crysis obviously
"But can it run Crysis?"
I find it more
impressive if a game can do a lot with very little power than if it
requires a lot of power to look stunning. I've seen Carrier Command run on a 128k Spectrum - now
that impresses me.
(The other side of that discussion, too: If something looks phenomenal but renders one frame per second... it's
graphically impressive, sure, and when the hardware catches up it'll run it well, but should it really be included at that point? And when you start following
that train of thought - well, games that run at 30fps have twice as long to do stuff as games that run at 60fps, so should we factor that in? Are we judging based on a single static scene - in which case you may as well nominate Myst as a viable candidate - or based on continuous performance, in which case framerate on identical hardware should be factored in.)
My point is: There's a shitload of metrics and discussions that would naturally surround a topic of this nature, and the hardware is inherently a component of it. I have a sneaking suspicion that the answer would be different depending on what system and settings you're using for each user!
