it seems to me that VC console games should base on the rating/sells of the game when it was around physically i.e. cartiage.

look at sim city...thats not really worth 800 pts
if it were sim city 2000 maybe.

i couldnt imagine anybody paying 1000 pts to download something sorry like SUPERMAN 64 (worst game ever, imo)

so basically,

nes 500 pts MAX
SNES & Sega 800 MAX
n64 1000 Max
