Why does this subject keep coming up?
1) You need HARDWARE to do certain "THINGS"; CREATIVE PROGRAMMING will only go SO FAR!
If you only have 88MB of total RAM, your texture sizes - AMONG OTHER THINGS - are going to be limited. If you only have ONE ~750 processor, it WILL NOT BY ANY MEANS BE ABLE TO DO WHAT A MACHINE CAN DO WITH THREE OF THEM. PERIOD, END OF STORY, SIT DOWN.
If you have never built a computer for yourself, never, ever talk about hardware capabilities again. Do you just look at the systems and say, "Hey the Wii's plastic shell is box-like, the 360's is box-like, and the PS3 is somewhat box-like... HEY, they must all be able to do the same thing!" It actually does matter what's inside said box, FYI.
2) Do you actually think that NINTENDO the people that MADE THE SYSTEM, missed accessing a whole processor when making SMG? Do you really think they only used half of the Wii's system memory? On their flagship game? Seriously, think about that for a second... how much better REALLY will any game be - GRAPHICALLY - than SMG? I really don't see it being improved very much over that. Unless someone here can give me a good explanation on why Nintendo would intentionally not use as much of the Wii's power as possible for SMG (FLAGSHIP TITLE), then I will continue to believe that SMG is pretty much the top of the food chain.
I think SMG looks great, but don't under any circumstances think we'll get anything even remotely close to Crysis/UT graphics-wise with the current hardware.
