Sorry, I should add a couple of details that might matter. We need a version that supports local network play, because we want to host our own matches without relying on public servers. Also, ideally the download should not require Steam, since two of my friends do not have Steam accounts and we would rather avoid that whole setup. And if possible, it should be a single package that we can copy to several computers, so we do not have to download it separately on each machine. Thanks again for any help.
