I think you are misconstructing my words here. I was not saying that M64 got such appraisals because it was so much better over other, older Mario games, but becasue it was much better than the games of it's time (Crash and whatnot...)
Actually SM64, and so all its reviews, were out before games like Crash, SM64 was the first 3d platformer AFAIR.
Also I said "how could SMS possibly be anywhere near as big a jump over SM64 as SM64 was over all other Mario games
and indeed all other platformers?". SM64 was a huge jump over all platformers before it because it took platforming into 3d and did it extremely well (like GTA3 took that type of game into 3d). Therefore SMS could never do anything as revolutionary as that and so was rated worse even though its a better game. GTA3:VC will not do anything as revolutionary as bringing to series into a full 3d world, so its likely it won't get as good an overall score.
The thing with GTA:VC is, there was nothing in the meantime that upped the ante. They are upping themselves, actually.
IMO nothing until SMS upped the anti over SM64 either, better visuals yeah, but not better games.
The fact is though a GTA style game in full 3d is no longer "OMG how cool, I've never seen this done before... ect ect", its old hate now with GTA3 and Mafia. I have no doubt that GTA3:VC will be a better game then GTA3, but just as you said earlier:
"I was not saying that M64 got such appraisals because it was so much better over other, older Mario games,
but becasue it was much better than the games of it's time (Crash and whatnot...) Is SMS that much better than the games of it's time (Sly Cooper, J&D)?"
Well GTA3 was SO much better then any similar game of its time (GTA2), partly because of a full 3d world. Will GTA3:VC be similarly better then the more current games of its type (Mafia and GTA3)?.. deffinately not, mainly because the leap to full 3d has already been made in GTA3.
