Been waiting for this one.. one of my favourite games Jazz Jackrabbit..
I realised not long ago that there was a sequel I didn't know about, and it looks like a really high quality game and major improvement on the original.
And a third (3d) game which unfortunately was cancelled.. it actually looks quite good, especially considering how many 3d efforts that actually were produced ended up being huge flops (looking at you Bubsy 3d).
Mortal Kombat II - one of the greatest fighting games ever made. How awesome was it? All the blood and fatalities, just pure gore. It took what Street Fighter had and made it better, something no one thought was possible.
Wacky Wheels - I remember back in 1998 I had a computer but really liked Mario Kart but didn't have an N64. Well... this game was probably about as close as we could get on DOS. I spent many hours on the shareware version of the game
