Yeah, put your hopes on a hypothetical mod team to create a hypothetical mod for a multiplayer you literally know nothing about yet, instead of on the spiritual successor that is being developed by the cRPG team.
You're being defensive here. I don't have a lot of hope that, with their failed kickstarter, they will produce a particularly good game.
I think the mount and blade team, will produce a good game; their track record - i've liked mount and blade, and i've liked warband.
I think that a mod building upon (presumably) a good product (which hopefully bannerlord will be), will probably be more fun than a "spiritual successor".
Planetary Annihilation was a spiritual successor. Lord of the Rings War in the North was a spiritual successor. Elite: Dangerous, was a spiritual succesor. A lot of the time, spiritual succesors, are not as good as their original mods/games. A mod, however, is a lot easier to make than a game, and thus, a better chance of being good.
Although, of course I hope the spiritual successor game will be good.
