Didn't you read the end? He is a brave bastion of sanity against the rampaging hordes of deluded Sonic the Hedgehog (2006) defenders. How dare you judge his noble work!
I have a friend who's REALLY dumb and still thinks Sega makes good games, and he was over at my place playing this game, trying to get the achievements in it, it was making me so god damn mad that I almost turned off the stupid Xbox so he would stop playing. He should have been able to beat that lava level in about 3 minutes, but Sonic would just keep stopping and fall and die and he would have to start over. The glitches here are not the exception for this game, they are the rule.
Sega still does make good games, they make Yakuza, and Valkyria Chronicles (which is full of JRPG stuff, but a damned fun game bescide it all). When they want to, they can still actually make a great product.
With sonic games, they know they don't need effort. They know damn well they can half ass any kind of crap, and there's an army of furries just waiting to buy it. Sometimes I think they makes these just to spite said furries, or the programmers are trying to kill the series so Sega lets them do something else.
I think my favorite parts here are the scenes where the player dies from going the correct way. Those speed boosters seem like a 50/50 chance of death.
