However, if talking to mainstream/casual gamers I would say Dreamcast. This thing is practically unheard of to most casual gamers. Yet casual gamers still find the gamecube relevant because it lasted a fairly long time and it is backwards compatible with the Wii. Yet if you bust out a Dreamcast with a decent library most people fall in love. Casual gamers adore simple games like Chu Chu Rocket, Sega Marine Fishing, Crazy Taxi and Virtua Tennis. Yet, there are enough hardcore games like Code Veronica and Skies of Arcadia to please naysayers.
So my answer is both...it just depends on who you ask.
Koopa, you should be so lucky as to 'fail' as well as GC did. Lol.
I didn't mean I didn't like it, I meant it failed in the general market. It might have helped if it didn't look like a big cube. What the hell kind of name is Gamecube? It was a good system, though. Dreamcast is just better.
