I was really - really hoping this game would be awesome. Let's face it, there hasn't been an awesome Sonic the Hedgehog game in almost two decades. Ultimately, this game turned out to be only mostly awesome; but that's good enough for me, and certainly more than we've gotten in years.
The daytime levels are just as incredible - if not more incredible - than anything I ever played in the original Sonic games. These are the reason I bought the game, and none of them disappoint. You've got all the classic Sonic stage elements here; bumpers, loop-dee-loops, and rails. This part of the game feels like a strange combination of Super Mario Galaxy and Excite Truck, and for me, that's a good combination!
During the day, the world fly's by and looks great doing it. The game moves only at 30 frames per second, but it is a very colorful, vibrant, and beautiful 30 frames per second. The speed is also complimented by excellent level designs. With the rare exception of a few poorly placed obstacles here and there, there is never a time where you feel that dying is just part of the game (as it occasionally did in Sonic and the Secret Rings).
They haven't gotten the controls perfect yet. There were a few times I inadvertently flung Sonic over a cliff through no fault of my own (most especially in the Adabat stage), but the control this time is a solid 90% as opposed to the 60% in Secret Rings and the flat out 0% in 2006's Sonic the Hedgehog disaster. For the most part, Sonic Unleashed is very playable.
If the daytime racing stages were the whole game, this would have been a five star review. Unfortunately Sonic Unleashed is actually two games. One is during the day when Sonic races around like mad; the other is at night where Sonic lumbers around as the Werehog.
Sonic the Werehog is essentially a platforming tank, able to bash enemies, climb up polls, and...bash enemies some more; its not that the Werehog is necessarily bad, just pointless and overused. The nighttime stages can be fun, but unlike the daytime stages I can't imagine ever playing them more than once, and what's worse is that you get three Werehog stages for every one hedgehog stage. The game simply never strikes a balance; the Werehog to Hedgehog ratio should at least be 50/50. Instead, the game is roughly 70% Werehog, 30% Hedgehog, and personally, I would have easily settled for just the 30%
Again, its not that the Werehog or the nighttime stages are bad - they're not - the problem is that no one is playing this game to do anything but speed through the courses. The Werehog levels simply don't amount to anything more than a decent platformer, and if it's platforming you're looking for, I say play Super Mario Galaxy, not this.
Still, everything that was great about Sonic the Hedgehog is great again here. This is ultimately what I like to call a good game plus. It's a good game, plus a bunch of other things that not only did we not particularly want, but that we never even asked for.
Don't get me wrong, Sonic Unleashed is a great game. But if you play, play for the racing stages, and leave the Werehog on the leash.
