In no particular order: StarCraft 1 and 2, Metroid Fusion, RuneScape (don’t play anymore but lots of fond memories), Undertale, Stellaris, and Divinity Original Sin 1 and 2. But if I had to pick just one it would probably be StarCraft 2. I was never that good at PvP melee but I really enjoyed the campaigns and custom maps.

Deus Ex

A perfect depiction of a pipeline from jack-booted liberal to revolutionary. Also, the game’s fun too.

hollow knight, hades, and starcraft brood war are all timeless
