If a new player were to join, would he receive a new party or would he have to somehow join another player's party?
You'd join an already existing party, IE, along with another player.
Will the election system be the same as in today's Germany, that is half of the Bundestag is elected in first-past-the-post system and the other half is divided between the parties on the basis of their percentage?
Yes, with a touch of the system in Norway, which ensures regional disparities do not cause overhang seats nationally.
Another question...do all the parties start with the same electoral base or there are ones more "favorites" and with an easier path to victory? I mean, those who have had more seats in former parlamentary elections according to the History you created...
And good luck to all!
Some parties will start with more seats, and, in better positions in the polls. This is balanced out by long-term growth potential, coalition possibilities, and trust or distrust of the various parties. All 5 parties have an equal "chance" to "win", but their routes to "victory" will be very different.
Sounds interesting, can I still join?
My preference would be for the fundamentalis, bible thumping, creationist Christian party.
The Conservatives may suit you best
