Names are not decided by vote. They are decided by someone posting something and lots of people saying "wow, that's it".
The problem with that is that BattleMaster is so very much what you bring to it.
For some people, it's a strategy game.
For some people, it's a game of intrigue and politics.
For some people, it's an economic sim.
For other people, it's a sociological experiment.
For still others, it's a lightweight framework for roleplaying within.
I think that trying to find one brief marketing-friendly name that truly encapsulates all that BattleMaster is is simply impossible. The game just has far too much scope for that.
