Great to have a forum about R3E!! Is there going to be a online lobby we can create on our own? Maybe create championschips in there aswell? Or are there only going to be prefixed race lobbies?
They said in a Livestream that there will come Dedi Server for the game, so yes you can set up you own Server in the future.
I don´t know, I heard it only once at the LiveStream. Maybe they writen something about it somewhere, but I only know that from the Livestream.
Custom championships are in the works. Livestreams are uploaded to YouTube. Here's the latest broadcast, the dedicated server is discussed around the 30:50 mark.
