1. Crush 40 has some nice riffs but abysmal lyrics. Seriously, it's embarrassing to even listen to.
2. There hasn't been a good Sonic game since Sonic Adventure 2. I'm being generous; the last one I enjoyed was Sonic & Knuckles, but I realize Sonic Adventure 1 & 2 were decent games... just not my type of gameplay. Everything after that, though, is garbage; don't take my word for it, ask any true gamer who isn't a Sonic fanboy and/or furry.
In the end, if I want a hack-and-slash game that's actually FUN, I'd go play Chaos Legion, or better yet, Ikusagami. Hacking through 65,000 on-screen enemies at once with nary a trace of slowdown > this crap.
