PlanetsCentral

Well snouka, there are some problems here.

You can't force people to have a deciding war when the two strongest races have 200 planets and ships each. Making proper turns in such situation will take too long and there is even no clarity that any advantage could be achieved in long period of time.

And there is a race like Tholian with main tool or feature to stop/slow any offensive. Forcing other players to attack Tholian directly (to battle it out) is like adding value to webs. Do you see it? Same as making any economic winning condition will add value to economic features and so on.
