Think of it as being a member of a secret society that doesn't allow idiots to join!
OP: Ehh, the problems the Vita and WiiU have are totally different than the problems the DC had. The problem with the Vita and WiiU is that it's great hardware but Sony and Nintendo assumed the success of previous consoles would carry over and slacked on good game support. The Dreamcast had amazing software but was destroyed by rampant piracy caused by Sega cutting corners on hardware because of the whole 'financial shambles after the failure of the Sega CD, 32x, Saturn, Game Gear, and Nomad' thing.
