Some initial quick impressions after completing the intro 2 main missions and 1 side op:
Intro is absolutely insane, one of the best I've played in gaming I was glued to the screen through the entire thing.
Controls are really nice much improved on GZ stuff like snapping to cover feels really smooth.
D-Horse controls great.
Having not played PW the fulton system is awesome, love watching things fly up into the air.
Troy Baker is great as Ocelot imo having read stuff about his accent I actually like it. Robin Atkin Downes is fantastic. BB hasn't really talked much so far but it's not a problem for me.
Mother Base is fucking amazing, I cannot wait to expand it and build an army. Just standing there watching Heli's fly in to the LZ is amazing.
Probably forgot a ton more that I've done but yeah it really is as good as you imagine it is. Gonna be my goty without a shadow of a doubt.
