Last week, we covered the 20th birthday of the Sega Genesis. The Genesis is one of the best vintage systems there is, and remains popular even now. Sega ran a poll to decide which Genesis game would be released to Xbox Live Arcade, and the poll is over, with ToeJam and Earl the clear winner. It's good to know we have some alien two-player co-op in our future. But let's not forget some other quality Genesis co-op titles of the past.
