Ngl, I'm not a fan of RNG for apps. I think it should be first come, first serve. I feel like there's too much room for potential mod favoritism with RNG (mods could fudge the results to benefit their friends and not tell have to tell anyone), and if you're going to go that route, you might as well just have mods pick the the best of the best apps. Which also has room for subjectivity/mod favoritism but at least then you'd know the mods were picking the apps.

I still think first come, first serve is the best option though. Mandatory tdm is intriguing but I don't know how it would work in practice.
