At goodwill today I got this mind game call Nemesis Factor that I thought was some sort of Simon clone. It wasn't though it's a puzzle game that twists voice, color and numbers into mind games. It's pretty cool and was worth the $2.50. If you see it out there pick it up it's addictive! the first 20 levels teach you how to play so the need for instuctions are nill. It also keeps your score and last puzzle in memory (up to five players) so the next time you play you are at your last puzzle.
