Everspace is a run-based space sim with randomized levels. You accumulate resources, some used for crafting and repairs during a run, others used for permanently enhancing your pilot and ship. The progression is satisfying, and the game becomes more fun as you venture further and further into space. Everspace has a story that makes sense out of the structure of the game. It is slowly told through cutscenes, triggered when you proceed further than you have before, and through logs from crashed ships.
I've been working on upgrading my Pilot to maximize what I get out of each run. Going for loot multiplier first seems like the way to go, then Nanomachine upgrades and recently I've started on critical hits.
