Well, I'd like to ask some questions about how multiplayer modding will work.
Can we make custom gamemodes, factions and units, with people being able to join servers with these mods without having to install them, so long as we only use vanilla assets? In other words, are there in-game tools for creating these sorts of mods? Can those tools, if they exist, also be used for creating new systems such as recreating the warband equipment system?
If not, have you considered doing auto-download, as most games with multiplayer modding communities do?
