Made turn based - locked to 6 players now, server should set player
count on start up? Could increment/decrement as players join and leave
but current design is inteneded to permit players to join / leave and
continue game later (as long as Server stays up, or persists game state
and restarts) - thus locked number of players from beginning of game.
Need to add boolean 'player active' to account for defeated or
capitulating players.
