Hmm. I guess this is my first proper post here.
I don't consider the Werehog to be worse than the Mech Shooting at all. Mech Shooting was like Gamma except if the platforming was unbearably clunky and heavy. When you're not going through annoying platforming parts that kill you for the slightest mistakes(damn death pits), you're simply mashing the fire button for way too long. Maybe if there was less Mech levels it'd be more refreshing and forgivable, but nope. They're just bad, boring levels that don't even quite qualify as mediocre.
That's not to say that the Werehog doesn't have it's problems, though. In fact, it's pretty flawed. The controls are really annoying, mostly for simply running around. I'll be going to jump onto a platform, but I'll be facing the wrong way. I move the analogue stick in the direction of the platform and hold left trigger so I can get there fast. Watch as Sonic goes left and plummets to his death. D:<
And his jumping is pathetic. I shouldn't need a double jump to get over EVERYTHING!
While the fighting is ok, it still has issues. 1, the controls aren't perfect. It can be hard to pull of moves, as I tend to watch the animations, not my button presses. What I mean is that I'll know I have to press A after two punches. I'll press A after I see Sonic throw two punches, not after I actually press the punch button twice. Though, this is probably more my fault than the controls' fault. 2, there's WAY too many fights. After a while it actually begins to feel like a chore to fight off hordes upon hordes of enemies. It's quite disappointing after just defeating a bunch of enemies, to open a door and see even more. The last major problem with the Werehog is that the levels are REAL long. Getting a game over halfway through is maddening! Sonic's death scream accurately represents how I feel at the time, actually.

Unlike the Mech Shooting, however, there's actually redeeming qualities to the Werehog. The platforming is actually fun! The stretchy limbs make you feel like Spiderman, and aside from some dodgy controls, it's actually pretty fun to navigate through the levels, jumping on platforms, pushing blocks, walking on tightropes, swinging on poles... it's not half bad. And the fighting is fairly fun, it's just used far too often. I generally have at least a little bit of fun while playing these levels, which is more than I can say for Mech Shooting.
I'm not sure why people would rather play Mech Shooting. It's so repetitive and, well... unfun. Well, I suppose at least the levels aren't
marathons...
