Personally, I prefer proportional elections. But as there never was any support for that idea, I stopped promoting it ages ago. So, we'll most likely keep the regions.
I'm all in favor of scrapping the separate regions and districts thing, though.
I totally agreed with PR in the case of real life. But in the case of fantasy elections, it wouldn't be very much fun....you wouldn't have all the different candidates and campaigns, and since we know everyone's party affiliation, the results would be extremely predictable.
It doesn't really matter who WINS the fantasy elections. We should create a process that is the most fun and gets the most people involved.
