aaaaaaa,,,super shinobi - this game does not get enough love......i still remember the cheat for infinite shuriken. Think I remember all the secret boxes on the first level as well....
I thought the freeze battle was excellent, deserves a place in the top 10 at least.
Surprised not to see R-type in here tho - seems we forget those oldies.
What about longest boss fights ever? I think it took me like 2 hours to beat sephiroth in FFVII (or was it his mother, or something - its been too long)
