i have a link to the netplay download on my other comp, basicaly its a collection of scripts as well as a server program that will allow you to host up to 150 players on one server, so if you can make maps your pretty much set, save for the fact that i have yet to figure out how to make a pvp system, i need to get someone to try their hand at scripting players to act like events lol
if you like send me a PM and ill send you the link when i get on my other comp,
you would have to redraw the maps cuz it was set up to be easy for people like us to implement the scripts basicaly someone made a game for the purpose of being redesigned. actually really handy IMO
