Outer Wilds. not only is it a fantastic game, but the entire premise and gameplay is centred around discovering the world. theres no progression, the story is all diagetic and not quest-bound or anything, and once you know the world you cant really discover it any more (unless you forget)
something people havent mentioned yet but that i ran into as a problem: qmk doesnt support per-key lighting in the sense that you cant have specific colours for each key. it supports per-key lighting in the sense that you can do effects, but you cant set the alphas to be a different colour from the ergo keys, for instance.
