Trinitronity... please stop. I should be the one giving feedback on the roster' first impression.
Although, he's a bit right (keyword being "bit"), the FCs looks more like Sonic than original chars.
BUT! There's no such thing as a main character in MUGEN, and the game has "Sonic" in its name because its the name of the series.
See? I can give better arguments than you do, Trinitronity. And also, Neo, you haven't made TOO much bad decisions so it's okay... It's not like you decided to make a game named "Sonic" without having Sonic in it, or at least some characters of the series: At least you put Sonic and some of his most-knew friends and less-knew enemies. And having some (5, exactly) FCs isn't that important, it even give the possibility to try new chars.
Besides, Neo replied to me on Kirby the Dream Battle (the forum, I mean), and he was way nicer than what you showed with your screen-cap. Hence why I don't like what you're saying on his project, It's HIS project (keyword: "his").
