Blasphemy!!! Dreamcast ranks up there with the best!! You call yourself a gamer? You should be ashamed!!
N-Gage for sure... Just was an awful idea/design!
In terms of console i think it would have to be either the Sega Mega CD or the Dreamcast (really did not enjoy playing on that) :D
I wish i still had my DreamCast... it was SOOO awesome!!
