So, enough time has elapsed that we can think about closing the poll soon.
It looks like you guys are clearly: interested in another CS:GO event, interested in another UE4 event, and really intrigued by the 1024x1024 idea. So, we're going to do all of these (eventually)! I think two contests per year is reasonable, personally.
I have a further question:
1) Hostage or bomb defuse? Both?
