User blog comment:HS664/5 Super Hard Sonic Games/@comment-3190872-20130213002517

If I may offer my opinion, I disagree with nearly all of this. There are certainly harder Sonic games than the ones you've listen.

Sonic Rush is made shamefully simple with the boost button. I don't believe it bears any resemblance to S3&K. Poor enemy placement and, as you mentioned, the final Special Stage are the only things that give Sonic Rush a shread of difficulty.

Shadow the Hedgehog's level design is poor, and its mission structure is tedius. Tedius =/= difficult. Well, it's difficult on one's patience, but not as a game.

I agree with your description of Sonic Battle, but that doesn't make it a hard game. That just means it has a hard level or two.

Sonic 06 is borderline unplayable. That doesn't count. It's not even fair to consider that real difficulty.

Sonic Unleashed... meh, to each his own. I personally didn't have much trouble with it, but I can see how some people might.

If it were my decision, I would have put games like Sonic Advance 2 and Sonic Spinball on this list. But that's just me :/
