If that was for SSE, it might take somewhere near that for a download, but no. Steam confuses Skyrim and it's Creation Kit as the same entity, so if you uninstall one of them...
Apparently, people forgot how to make good Iga style Metroidvanias. Every non-Iga one I've played has not lived up. Save me, Bloodstained.
@Rei Novae That was how I also felt. I have yet to truly dig into it though. I haven't had the time. I wouldn't worry about missing the first burst of people. If you're interested in multiplayer, I'm sure you'll be able to find same-skill level people for a while. I'm solo, personally.
I've played some of the previous titles (MH4U and MHG), so I know what I'm getting into, School started a week ago so I wasn't able to go get the game, and homework is gonna make my world a pain.
