I submitted a question through Kickstarter, and they got back to me on it:
Will there be mod support?
Hi, [real name redacted] -
We found out what a huge undertaking it is to make an editor for players during Shadowrun Returns so, unfortunately, player-created campaigns/missions are not in the scope of this project.
However, Skirmish mode will allow you to set a wide variety of parameters for tactical combat. against the AI.
Sorry about that-
Robin
While not directly answering my question, it looks like what they add will be what they add, unless they go for expansions.
They said on the livestream, they didn't expect to provide any support for modded-in mechs either.
The game will be made in Unity 5. I think (not that I'm an expert) Unity games aren't generally easy to modify when all you have is the packaged, final version of the game, so without them dedicating any development time to mod support, we aren't going to see much/any modding.
Hey, unrelated Battletech question. I know there's a list of canon mechs, but what book are their actual stats in? I have a few Classic Battletech books, and the quick start rules have some stat sheets that are filled out for four different mechs as well as some tanks, and paper standees in lieu of miniatures. The Total Warfare rulebook has a an incidental list of mechs likely to be deployed by each house, listed by name without stats or illustrations. The Techmanual includes rules for weapons and equipment, but only for building mechs from scratch. Is there a separate book with all the official mechs listed, or do stat sheets come with the miniatures, or what?
