hmmhmh I have some, I usually delete games as soon as I'm done with them but I might keep some that either don't weight much or are troublesome to install again (modded games mainly)
-Civilization 4 (modded with RI)
-Darkest Hour (weights less than 1gb)
-Cold War Crisis (it's a fucking 2001 game)
-Medal of Honor Allied Assault (nice game)
-Battlefield 1942 and 2 (with tons of mods, this weights a ton but I play a lot online)
-Fallout New Vegas (has around 600 mods, 250 or something are things I can't merge like quest mods, the others are merged in 4 files and they're mostly items)
-Morrowind (Thanks god Morrowind has a 1200 plugin limit instead of the boring 255 of New Vegas, therefore I have around 800 mods in that thing)
-a shit ton of emulators.
-Arena Breakout (A friend asked me to play this shit, ain't bad but it weights almost 100gb lol)
-Some assorted games I really don't feel like listening right now.
I barely play any of this shit, but I keep it there in case I wanna play one day
These are the games I have spent decades collecting and tinkering with to get working on Linux.
yo wtf is this list man

it's amazing
