I'm not sure why my fellow commenters think this is a feature request.
Giving the game, a platform, only 25 gig is an issue, given the fact that most servers require a serious amount of storage to even play.
What is the technical reason for the 25gig limit?
100 gig is not the solution, thats a hot fix. Get rid of the limit or set it to some high number. Let users decide on how many mods they want or need.
I don't want to play Arma Reforger in vanilla mode. I want the real sh*t, like blue f***ing tape around my arm!
