Let me get back on Breathless. Technically it was very impressive, and it looked good, too. But play it again today and you'll see the gameplay is really bad. Enemies are all the same, level design is very simplistic (most of the time) and the only reason to continue playing is to marvel at the graphics. I think I even played it in 1x1 on my 030/50, which gave me like, 8fps or something.
I really cant agree with Mortal Kombat II, that was an excellent conversion.
