User blog comment:Lykrast/Moar for CUSTOM Games/@comment-7007348-20130409065528/@comment-5331854-20130727195957

Well, most of these are already implemented somewhere, so they just need to copy it and make it customable.

Most of these are basic stuff to implement (and I can imagine the staff sometimes play advanced custom games on a private server to fiddle around with ideas). It should only take a few days to make it happen and some more to get the servers ready, after that, it's patching time.
