Is there multiplayer?
Net Gain 1.0 does not have traditional multiplayer.
It's about you, rising to the top at the expense of all others! I would like to offer some pseudo-multiplayer options, though, such as sharing game-saves to play in someone else's world.
It's not entirely out of the question for some future expansion, and I am designing with the possibility of adding multiplayer in mind, but the current build is focused on making the single player a rich gameplay experience and adding multiplayer is far out of the project's current scope.
Is there modding?
My first goal is to make the game. It's still early to be talking about mods, but the game is built with most of the content exposed in data files, so it'll be easier to make mods when it comes time. I am *all* about involving the community in the development and growth of the game and setting, and after the core game is built I will do what I can to encourage modding and community involvement!
Is there localisation?
Sadly I cannot promise any localisation right now.
I'm just one (English-speaking) guy, but I would definitely like to get the game in as many languages as there are fans! The data is all in files so that will be easier to localise and could be opened to the fans, but I haven't built any such systems for the rest of the GUI yet. It's something I will be adding but it wont be in for the prototype release and I'm not sure if it fits in the schedule for 1.0. If there's a large fanbase that wants the game localised to their language, we'll figure out how to make it happen!
