actually all of the versions of esf work with WON, you just need to know how to set it up right. you can play with bots, but it's not as challenging as playing with others. anyways i doubt anyone will help you setup won because it's died and passed away a long time ago. online play is used through steam, although you can play lan games with steam. just buy half life and you don't have a problem.. anyways it is still very much possible to play with WON still.. heck i have two installed directories, one for steam and one for won. if my friends come over we play esf through lan, and using won is so much easier >_<
