I had to redirect my post here, so mind the repost.
"MCC is a collection of games where you will undoubtedly download a bunch of community created files. One solution to changing the limit is to make it a 50 MB or higher limit instead. 50 MB will probably be enough to download a bunch of community maps, since they are pretty small in terms of space. If that doesn’t work, you can try making it an option to change the size of the space you want to dedicate to custom files. We will just have to see. The reason why to change it is because again, MCC is a collection of games that you will make a bunch of forge varients and also download a bunch of varients and gamemodes from other people. I am not making this post to harass anyone at 343i, I am making this post because this is a thing that has been dragging down MCC’s Custom Games."
