RimWorld, Subnautica, darkest dungeon, streets of rogue, project zomboid, oxygen not included, starsector, skull the hero slayer, dead cells, caves of qud quasimorph and universim are games i bought in early access that I do not regret in the slightest.

I'd say the biggest problem is these big companies who release "finished" games that are clearly not finished and the people who keep pre-ordering them
