All the Mega Drive Sonic games. They have aged awfully and are filled with plain cheap difficulty at times. I can't stand them.
Actually, you can throw just about every Sonic game apart from Sonic 1 Master System, Adventure 1, Colours and Generations onto that list. And even those last three are no more than good in my book. Almost every single Sonic game is filled with cheap difficulty and I can't stand it.
Sonic 1 MS is just a special exception, freaking love that game. MS 2 though I despise with a passion.
