Calling the GameCube bad because it didn't have enough games doesn't fly by me. In the time I had mine (first picked it up when it was bundled with the GameBoy Player for a discount) I never had enough money to even buy all I wanted, so the lack of games is not a credible argument by me. The games I got simply weren't available on the other systems (at least not optimally - Resident Evil 4, REmake, and Zero were all either downgraded or no-shows on other systems). That said, I did feel that I didn't get much value out of it - nowadays I'd almost rather have a PS2 for the (much) larger library.
hurdurrrrr Contra III, Super Castlevania IV, Ninja Warriors Again, Pocky & Rocky 1 & 2, R-Type III, yeah totally not worth it (and that's just non-Capcom, non-first party stuff that's been on my mind lately; with the GC I struggle to list more than that many good games for it period - basically the Zelda games, the Resident Evil games, and Metroid Prime 1 & 2)
