Alright, let's see how many I can get.
Minecraft
Rimworld
Rust
Mount & Blade
Subnautica
Terraria
Running with Rifles
Starbound
If you'll let me count games that are still in early access but are already pretty damn near to being fully completed, i'd like to add:
From the Depths
Factorio
There, 10 games. It wasn't that hard. Most are in my steam library, and appart from Mount & Blade the original I played all of them. I doesn't mean they were games that necessarily suited me or what I like to play, but they are definitely in a playable state.
