If you wanna start an 8.6 rlmap, then go with 1.2 (the one Ninja released), avoid using the older 0.x versions.
Or go with a 10.x server, but you have to do more things, compared to an 8.6 server to get it "good", but would generate alot more players if you do make it 10.x.
Just look at shadowcores and the ox server, shadowcores is slowly gonna die out, just like icechaw etc so id say it's a good time to start a 10.x server.
But what most ppl are doing is downloading the github one and starting it, thats a big no if you ask me.
It does have alot of bugs, but for some reason ppl just wanna make money insted of a good server and earn money from the work they did...
