Time for me to be slightly controversial, although not in any real order:
1) Turrican 1
2) Sensible World of Soccer '96/'97
3) Fantasy World Dizzy
4) Speedball 2: Brutal Deluxe
5) Indiana Jones and the Fate of Atlantis
6) Worms
7) IK+
8) Rodland
9) Archon
10) D/Generation
You'll notice no Turrican 2 on there. I have a really hard time with Turrican 2. Love the music, graphics and gameplay for the most part... but that STUPID FREAKING BOUNCE GUN.
I hate that bounce gun.
