I find the Defined Roles gamemode really interesting and innovative. I'll give it a try, but the idea of each player having a specific purpose sounds more adapted to multiplayer team games than what is currently proposed (where each player simply builds his own little fleet)

The number of races doesn't make a difference. But there are several settings that are configured for each player. So that's 2 extra players for each of these settings.

That's a shame, any idea on which two races you might remove (PTV varients perhaps)?

I was hoping to port this mod to the new engine, but there's a limit of 32 game rule menu options, and the extra 2 players in HWRM puts this mod over the limit. :(
