u smoking crack?
GC was junk. The greatest advantage it held over the competition was price and to laugh at how GameStop would only give people about $30 trade in credit for it in 2003.
1st Party Games? Bad. Probably the worst iterations of the Nintendo franchises out there. The only exception was F-Zero and SSB Melee and the latter is just barely passable (only reason why it gets mentioned is SSB Brawl is worse). Nintendo really dropped the ball, sucked the dick, etc. on the software front. Probably why nobody bought the thing. People buy the systems for Nintendo games. People didn't buy the GC because the Nintendo games on it were ass.
3rd Party Games? Sparse. We got the Capcom 5 which didn't materialize to anything. We got Symphonia but oh wait, you could get that on PS2 the following year. Same goes for RE4. Most of the good GC stuff went to the PS2. All you had to be was a little patient because you knew that six months later, a PS2 version hit the shelf. Take those versions away and the GC exclusive front was sparse at best. Remember those six month stretches of one or two releases?
What did GC add to the table? Little. The GBA connectivity was a joke. In fact, Nintendo seemed to give up on the GameCube entirely and once the DS started hitting its stride, sales wise, Nintendo forgot it even existed. That should be a cue that even Nintendo didn't give a fuck about the Cube. Neither should you.
