Most sonic fans detest his nickname "Eggman" as opposed to Dr. Robotnik because the latter sounds more evil while Eggman makes it comical, although Eggman has been his ame in Japan from the start. His VA does an amazing job voicing him as well. But hey don't let my bashing stop you from playing it xD. I just thought it was bad. Battle was a great game indeed, I loved playing with Cream obviously and I'm still trying to go for all A-rank on Heroes.
Ah, lazy....sleeping all day lol. Well I'm not one to talk actually :|
