200 hours? That seems like an exaggeration but if you're certain it's true then wow. Haha.
I've been modding in this community for a long time and I can honestly say I doubt that even I have done 200 hours of working in the level editor. But if you're looking for something to do, Cry is hosting a 24-hour Custom Story challenge. Perhaps you've already been to the thread, but if you haven't check it out. It'd be a good way to get some work out there.
A lot of collaborated projects in this community seem to fall apart far too easily
