Like you said, most of the characters haven't been in a game for 5 years, they may seem obsurce, but to Sega fans, they are not. It would be a terrible game in the Sega All-Stars series if it had no Sega characters. Also, the Chus were in ChuChu Rocket!, a well-known Dreamcast game, and a lot of people know about Alex Kidd and Opa Opa.
