I was a hard core gamer with the PlayStation and Saturn and STILL missed so many great games. There is only ever so much money available so some had to be pushed to the side for others to come home.

That is the great thing about retro gaming, finding that hidden gem we never heard of and may have passed on back in the day.

Clockwork Knight is slower while Pandemonium can be frantically fast. I think the spee of Pandemonium is what turned me off personally (I only liked the original Sonic too so there may be a connection there).
