Microtransactions are purely cosmetic and as far as I could see at eververse it was only some shaders and things like that so I ain't bother with it. Plus you get some with blight engrams.
The story is kinda flat and straight forward (brings me back to Halo 1), but compared to D1 (was there a story?) it's pretty fun and it's just for levelling your character anyways to get ready and play that end-game content, it really feels like a console MMO game.
I will review this game again after a month and see how much work Bungie will continue to put in, because content was the biggest thing lacking in D1.
