Seemed like a good match at first. I thought they'd at least get it together for M and S Olympics, but that seemed like a cash-in. The first Sonic game had potential but had issues. I thought they'd at least expand upon that. But nope
Sonic Boom could have gone somewhere, but I'm guessing the studio wasn't that great to begin with, Sega saw what was happening with the Wii U, thought screw it, cut our losses, hurry up and release what you have and we can do our own Sonic thing for the other consoles.
Thing is, I have a feeling Sonic wont fare much better on the PS4/XBO. Well gameplay wise it;ll be at least decent, but I don't think it will sell tons.
