i've always played and hosted a jailbreak server, right now we're still hosting 0.6.
Though i have also played and hosted the following:
Insurgency
firearms source
hidden source
neotokyo
golden eye source
wwi source
zombie panic source
source forts
fortress forever
*****
i stopped looking for hosting when my group started up and began looking for tools to controll the server(s).
yeah - i know the response didn't mean much. I was more responding to mods that i've seen to well.
and plus - to clear up a bit of the "jailbreak" confusion as i know some people here are jail players::::
