How to make a Bannerlord mod
and not be a snotty attention whore
0. You prototype your mod for Warband
That way you get feedback for gameplay changes and models. Are your models bad? People will tell you. Are your gameplay changes kooky? People will tell you immediately.
You also get name recognition, important for the future.
1. Bannerlorld is released some time in Spring-Autumn 2014.
You play with it and look what players are saying and learn how to mod it. Attention whores are starting their short-lived mods immediately, but you can wait until you have something to show.
2. Few months later.
You convert your models from Warband, include some OSP models, make some scripting tweaks and release an "alpha". People say it's the best mod ever, but they say things like that, and better mods are already in development.
3. Several months later.
You succeeded to attract experienced or talented modders that were drawn in by the quality of your work and the initial popularity of your mod. Now you have to finish it, and that's the hard part. You need to work on things that are no fun for you, manage a chaotic bunch of online contacts to get results, and always keep and communicate a vision of what your mod is all about.
Ideally, you hit on the playability features that Taleworlds missed, your models are interesting and good enough, and you release a proper 1.0 version. Congratulations!
That's how you make Bannerlord mods, not by starting clueless, attention-seeking threads like this.
