Destiny 2: Curse of Osiris Thoughts
I honestly kind of hate Mercury? It's one circular courtyard that serves mostly as an entrance to the one big building, the "infinite forest", which is basically floating beige bricks in a cloudy skybox. It doesn't lean in enough to either its "computer simulation" or "branching timeline" motifs and just feels like a box for aliens to live in.

I don't really think it's worth $20, but I bought the complete version to begin with (like a dummy!) so I didn't have to make that decision. Of course the trouble is that if you want to get into Destiny *now* you pretty much have to buy it if you want to do endgame activities with friends. That's MMO pricing I guess.
TLDR? Just... don't do Destiny
