Since I mostly listen by dropping a whole genre into an ephemeral playlist, there is zero overlap. I rarely even hear a piece more than a few times a year, and sometimes the whole playlist takes more than a year to play from 0 to Z at an average of 1 hour play every day (eg I have pretty much the complete catalogue of Ektoplazm, including 575 goa trance and 377 downtempo albums).
Even if I have a few static playlists of random pieces, they’re also thematic (eg a bluegrass playlist as background music for dogfighting) and with zero overlap between them.
Come to think, of it, I only have two static, saved playlists—one for dogfighting and one with pieces that have subbass and ULF content down to and below 20 Hz. Playlists for me are wholly ephemeral, the default one that gets cleared and refilled as I go, acting more as a playback queue, and temporary ones that get deleted when I’m done with them.
Elder Scroll series. Skyrim for the modding and eyecandy potential, Oblivion for the madness that is spellcrafting (also Shivering Isles is the best ES DLC), Morrowind for the true alien fantasy.
Thief II is the quintessential first-person sneaker.
Independence War II still has one of the best flight models and a great story.
X3: Terran Conflict is the best first-person strategy game.
Half-Life 1 and 2.
Il-2: Great Battles is the best WWII combat flight sim.
DCS is the best jet combat sim.
Elite: Dangerous is the only space sim with actual 1:1 scale galaxy, including many real-life stars and is the best life-in-space simulator with flight model as good as I-War 2 and decent enough on-foot parts (even though there is some jank and glitches).
