There are so many tbh, really depends on what type of games you're interested in. I've really enjoyed remnant 1 and 2, owlcat pathfinder games, VRising, Riftbreaker, Timberborn, Against the Storm for example. All made by good dedicated studios that deserve your money more than EA, bioware, actiblizz or other corpos like that. Of the older titles, FTL, Into the Breach, Stardew Valley, Hollow Knight, Factorio, Project Zomboid etc are classics - polished games made with love that put pretty much every AAA title to shame in comparison.
