Yeah, there's a lot of settings I don't like. I hate either type of freestyle game, and really hate unlimited fortifications games, and am pretty unfond of team games. So create your own game. Sure, it might take 12 hours to get started, and will probably be populated by newbies, but at least you'll get to pick your rules.
But your point is valid, why would someone play "with double turns" unless his goal was to take double turns as often as possible to get a victory he couldn't earn through strategy and patience?
