A bit late for an introduction, but I like the idea, so here are my #7GamesToKnowMe:

- Realms of Arkania: Star Trail (the original, not the remake)
- The Settlers 2 (the original, not the remake)
- Kerbal Space Program
- Transport Tycoon (explicitly inlcuding the OpenTTD remake)
- Dwarf Fortress
- Cultist Simulator
- Dominions 5

(Edit: Just to clarify: those are games I enjoyed playing, not that I worked on as a dev.)
