What? Aside from that though what is a "GC" exactly?
gamecube.
also better hardware is definitely a worthwhile improvement. you can make software on a 3DS that would be impossible (or much worse) on the older DS hardware. the 3DS has a stranglehold on the mobile gaming market (excluding smartphones), but that's mostly because it has good games.
and uhh rly i guess that's a good point, we're all talkin about hardware when what rly matters is how many Kick Ass. memorable games run on it. which is why the wii u didn't do as well at first, there weren't many exciting titles. nintendo's real power is knowing how to make sure new consoles launch with games people care about, and that's where they dropped the ball with the wii u. looks like they might be smarter this go around since they've already announced one game that's blowing people's minds
