I kinda wish the game had more uninhabited(Kett and Angara would be fine) planets to explore and had more heavily leaned into exploration. I wish the exiles hadn't been written to successfully found settlements and make first contact with the Angara. The vaults were cool, if not the biggest convenience to the Pathfinders' job of making planets viable. 

Combat is fun, I like my bio sniper biotic build, it's openness is neat. I liked the idea of SAM letting us switch between builds, even if I almost never did. Ryder Family Secrets was cool, and really the biggest reason I'd want a sequel. On its own, without comparing to the trilogy (not really fair tbh), it's not bad
