I have played both the Glasgow scenarios you created, and I have to say that they were brilliant. It was really interesting just focusing a campaign on a small group of constituencies. As a Tory the 1950's scenraio was most enjoyable due to the city being competitive. The 1992 version was also pleasing though as I managed to pick up two seats for the Tories in my first go.
I noticed that you were planning on a Liverpool scenario, and I wondered if you had considered an earlier election for this city as well, when it was also competitive. The 1964 election springs to mind as an interesting one as it was during this election that Labour gained four seats from the Tories with massive swings, leaving the Tories with just two seats out of nine in the city. Certainly an entertaining election!
Also I look forward to the creation of a Belgium scenario, a real variety of parties on offer there.
