I can make an ATRL server but I can't have it up 24/7 or my computer would fry, but I can host events if you want. No one lags in my servers (well, so far I've gotten 5 people in one and no lag so)
Are you willing to make an official thread with me as OP since I would be the host?
I only played the regular game for a while, where you have to survive in the wilderness and build everything from scratch. I always wanted to get into the custom maps but for some reason I never did.
