Sonic's current problem is Action overload (it's hard to watch something where events happen too fast and too much; Sonic had that from the beginning but it was normal, but then...) MLP's is... idk, but it's surely something serious. It seemed to regularly break its own canon lately. So? Don't know.
Not a big fan of sonic to be honest. I really liked SatAM back in the days (and still do.) But the games have been mostly shit IMO, which is a shame, since I want to like them, and some of the music have been really good. (Crush 40, I'm looking at you!)
