As of late, I've started to enjoy collecting Steam achievements from my favorite games (both campaign and endless). So far, I've only earned the blue-yellow ribbon of 100% completion in one, but that's fine :). And as for those favorites that aren't on Steam, yet have their own achievement systems, I'm planning to complete them as well!
And here are some silly stats from endless games: (updated rarely)
Minerals mined in Deep Rock Galactic: 171 857
Large monsters (probably responsibly) hunted in Monster Hunter: 236
Gs worth of product shipped in Stardew Valley: 488 037
Zombies killed in Left 4 Dead: 21 487
Enemies of Managed Democracy vanguished in Helldivers: 23 943 at the cost of 374 Helldiver lives
Author Medals earned in Trackmania: 68
Towns built up in Animal Crossing: 1
