I'm not sure if this has been asked before. My question is basically, would this game allow us to host our own servers, with custom mapping / scripting? Currently I am playing SA:MP and have been looking for a new game to play with the same customisable features of the SA:MP client

Sorry I'll clarify my question further. Thanks for everyone's responses so far! I was not referring to hosting one on my own PC, but instead having a private host on a private server box / whatever (I'm not too experienced with the terms used)
