Thought I’d take a stab at this… So, here goes: #10GamesToKnowMe (with system I played, or most played, then on) sorted by release date.
Star Wars: TIE Fighter (MS-DOS 1994)
Donkey Kong Country 2 (SNES 1995)
Command & Conquer: Red Alert (PC 1996)
Final Fantasy VII (PS1 1997)
Zelda: Ocarina of Time (N64 1998)
Dance Dance Revolution: Extreme (PS2 2002)
Final Fantasy XIV (PC 2013)
Cities: Skylines (PC 2015)
Hades (PS5 2018)
Fire Emblem: Three Houses (Switch 2019)
If the game is in a series or a “type” like for instance final fantasy, Zelda, cities skylines (city builders), or FF14 (MMOs), I chose the most meaningful one to me… I probably played and/or loved them all.
