it works like larger open source projects, with reviews and community feedback and reputation etc. As you might guess, getting a new feature pulled requires more work than fixing bugs(new feature needs to be really useful and polished). Bug fix pull requests are easier to get pulled in and generally goes down like this: you post a fix, people suggest how it can be done better or you need to get your fix aligned with coding conventions and then you fix the fix and then it gets pulled.

Also getting code into unreal tournament is much faster than filing a pull request to engine. Since like, it's in rapid development phase, and cost of breaking something is less compared to engine.

There is like ~200 merged and ~40 open pull requests on git right now on 4.2 branch
