I was a big fan of 4thcore. Some of those folks have moved on and now do some cool stuff for 5e. It is weird, I just recently heard about some kind of upcoming 5e competition series that is going to be live-streamed, then a few days later I was made aware of this. My money is on this being waaaay cooler than whatever the other thing is.
