That isn\'t a bad amount by any means for the GC, considering it had almost no hype and lacks a Mario title, which always sell on a 1:1 ratio with the system ( ala N64). The PS2 had so much damn hype behind it, including the hype Sony got from the shortage at launch that it was gurantee\'d to sell. However, there was plenty of terrible launch titles, unlike the GC launch which apparently has pretty damn good launch titles. Nintendo once again went with quality over quanity and I support their choice on that.
The smaller disc really isn\'t that much of a problem. The GC compresses textures at a good rate - I forget the exact compression ratio and if they need to, they can make it on more than one disk. No big a problem really. Did the GD-ROM hurt the DC? No, not really.
I personally doubt the GC ever matches the PS2 userbase, but why who cares? They have their gurantee\'d sales with younger children, people who love their franchises, christains who dislike violence and now they have the Resident Evil series which gurantee\'s some more sales. Overall, they are going to have an impressive userbase before the end of next year. Will it match the PS2 userbase? I doubt it, but it will be big enough to make the big \'N\' a ton of money.
