Personally, I wouldn't mind Ristar showing up but I think a Phantasy Star representation would be much more fitting.
My issue really is this game has just as bad balanced roster as they did last time. Of the 15 characters confirmed so far, 9 of them are from Sonic Team. We have 11 left and even if they are not Sonic Team characters, that would mean 35% of the characters are from one team. 4 of the 9 franchises confirmed so far are from the Dreamcast era, which is SEGA's least successful console era ever.
Obviously AM2 is not considered important by SEGA, their belief that even VF5: FS was a niche fighter in a niche genre shows you how much confidence they really have on their own brands even though AM2 have been by far SEGA's most successful team. With this is just continues to be a further knife in being a fan of the company, especially as the game is being developed for non-fans. Suddenly their opinion is just as or more important than those of fans who have been following the company for 20 odd years? Well glad to know SEGA are not directly targeting me.
It is a shame but I expected as much. After all SEGA for some insane reason believes that the Alien franchise should be one of their core brands when it should never be, it's only a license they hold.
Oh yeah, I have Yakuza 5 to look forward to and Virtua Fighter 5: Final Showdown should keep me busy until the end of the year.
