Most succesful Amiga games were ported to the PC or other consoles. I can't think of ten.
5. Tanx 'n' Stuff, a freeware split-screen multiplayer where you shoot each other with tiny tanks
4. Circuit Wars, a freeware turn-based game where you place wire and electronic components to try and send a spike from your base to your opponent's
3.
Odyssey, a platform game where you start as a swordman and gain the ability to transform into different animals to use their modes of movement, combat abilities and night vision. Metroid-like, in that one of the forms is a rock monster who rolls around to enter tight spaces.
2. K240, an asteroid-colonization sim, which was remade on the PC as Fragile Allegiance, but the original is still an excellent game.
1. Knights, a fun two-player freeware game where you run around hitting each other with swords and looking for specific treasures (also setting traps on doors and chests, smashing doors and chests with hammers in case they're trapped, smashing tables for no reason, and stepping on pentagrams repeatedly when your opponent is about to escape with the objective in the hopes of randomly teleporting to him)
