Someone messaged me here on the site about which Sega Master System games I owned. I think most of them are stored at my dad's house.
 
Anyway I think this is about it:
 Alex Kidd in Miracle World, Alex Kidd in Shinobi World, Mickey Mouse Land of Illusion (not to be confused with Castle), Donald Duck: Lucky Dime Caper, Wonder Boy III: The Dragon's Trap, California Games, Super Monaco GP, Sonic The Hedgehog 1 and 2, Krusty's Fun House. 
 
The crown jewel is obviously Wonder Boy III, an amazing game.
