Reinventing the CraftA project that aims to add more functionality to Warcraft III, while at the same time keeping it a low size, so it's still useful for mappers. RtC will be available for any type of map, mod or even a Total Conversion.
Maybe. So far it hasn't been tested in LAN (and we aren't too interested in making work in there if it doesn't already, at least not for the time being) so we don't really know. Some things probably work while others can cause a desync.
