Warframe had a very pay-it-forward culture when I played (Fortuna-Old Blood expansions). I got advice on meta starter weapons (Hek/Atomos) and Warframes (Rhino) and where to farm them. I got taxis to locked (for me) planets and direct help for some of the bosses. Other noobs were also helpful for the mutual revives. I even got some free trash mods from a clan member when they saw I was new. For spontaneous conversations I’d join clan parties or simple missions with lots of downtime (i.e., escort, wave survival). Endgame farms with specific roles and/or time gating like Eidolon hunts were very sweaty.
Halo CE has some real bangers (Devils…Monsters, On A Pale Horse, Covenant Dance, Under Cover of Night). Blow Me Away from Halo 2 has some amazing guitar riffs. The Starcraft: Mass Recall mod adds a lot of great music from other games/artists to its cutscenes. Starcraft Terran 1 goes METAL is probably my favorite out of those.
