-Exploring a world in 3 Dimensions by moving around and frequently jumping and changing platforms. I wish it was bigger and less theme-parky, but Reaper's Coast in DOS2 was fun to explore for the first playthrough and only got old once you had discovered everything.
-Having in-depth companions with party interactions, character arcs, and reactivity to character and decisions. Not a lot of games do this well, and it's nice to see the attempt at life-like characters being made here. The only companies making this type of experience are Bioware (not in a long time), Obsidian (not in a long time), and Owlcat (not necessarily to the same caliber), and some others that I'm forgetting. This genre has seemed to be on the decline for a while, and I'm glad Larian is putting a stop to it.
-Creating a character with a tie to the world and seeing the world react and my characters develop.
-Mid and Late game combat encounters that make interesting use of the 5e system.
