  1. Why are you guys always so needlessly pessimistic about the Lib Dems, no projections since the beginning of the campaign except for two days on electoral calculas have had them that low, it makes it so rubbish to play to as them, knowing you have to struggle just to get where they really are in the polls. Please put them up at the levels they actaully began the campaign at i.e. 10% in the polls.

  2. @Paul,

    Remember the numbers include 20% undecided, so add approx. 20% to their starting % to compare apples-to-apples.

  3. @Milo re endorsers,

    Thanks for this – should be fixed in next update.

    Re Labor underpowered, that’s pretty much where the polling was on April 18th. There was a very large difference between the parties, with some projections putting the Conservatives at 400+ seats.

  4. Wow such a great update! Cheers!

    Just a suggestion though, would it be possible to have a setting for debates to allow the player not to attend the debates at all? would work well for this election! 🙂

  5. @Will,

    Yes, will be fixed with next update.

    @Ed C,

    I set the debates to who attended or was expected to attend. A debate decline option is a good idea, though. We’ll see.

  6. Looking in the editor, Paul Nuttall has an id of herry_reid_2_2 as a surrogate for Nigel Farage.
    Nigel Dodds has an id of herry_reid_2_2_2_2_2_2 as a surrogate for Peter Robinson.
    Mark Durkan has an id of herry_reid_2_2_2_2_2_2_2_2 as a surrogate for Alasdair McDonnell.
    The Local Independent has an id of herry_reid_2_2_2_2_2_2_2_2_2_2_2_2_2.

    Also, South Thanet has some new about an expenses scandal.

  7. @RepInNYC,

    U.K. is not done. This is a first release for 2017. Will probably focus on it until U.K. election is done on June 8th.

  8. Also, is there a reason that John Bercow is listed as Independent for the 2015 election but not for the 2017 election? I know that on the ballot he is listed as Speaker Seeking Re-Election.

  9. @Jesse,

    He came from the Conservative party, and my guess is he would work with the Conservatives if not Speaker.

  10. @anthony_270admin do you have an idea what the ETA will be for france 2017 (I’m really desperate for some two-round campaigns)

  11. New version now available, 2.5.7b. This version will display 2.5.7 when playing. You will know you have it installed if there are endorsers for 2017.

  12. @Ben,

    Do you have a save game you can load that will reliably create the error within a turn (or so)?

  13. @anthony_270admin

    I do not, however it’s happened several times. I’ll attempt to recreate when I get some time.

  14. The 2017 scenario is very good, there are a couple of things I wonder about though.

    – Dagenham and Rainham, the percentages seem ok but UKIP seem to win a lot, I’m not sure why this is but it seems very unlikely they would manage this.

    – Not sure if Gerry Adams should be the leader of Sinn Fein, Michelle O’Neill is the leader for Northern Ireland even though Adams is the leader of the party itself (although I guess thats a judgement call as both played a big role in the assembly elections)

    – Is it worth having an event surrounding the social care fiasco as it does appear to have become the (or one of the) salient moments of the campaign. Maybe it could raise the profile of the NHS issue and give Theresa may some negative momentum?

    Really good scenario, I’m enjoying it a lot, just thought I’d bring up those couple of little things

  15. Ok, so my PMI before this update was painfully slow, almost to where it wasn’t fun playing. After this update, its excruciatingly slow to where gameplay is impractical. Is it just me or are more people having this problem?

  16. @Kevin,

    Can you tell me what your system specs are (operating system, memory, processor speed), whether you have autosave enabled, and whether you have any other programs running like McAfee or Norton?

  17. @Kevin,

    For comparison, the test systems I have here now run noticeably quicker with 2.5.7b in 2017 than with 2.5.2 in 2015, the previous version.

  18. @Kevin,

    However, the speed was fine with 2.5.2 on test systems here, so this might be something system specific or that you have autosave enabled, which certainly would slow down in-between turns.

  19. @Kevin,

    Also, can you tell me if it is just slow in between turns, or doing things like opening the strategy screen and so on?

  20. @270_admin
    is it possible that a sneak peek of two-round will be available soon even without a France 2017 campaign.

  21. Its slow both in between turns and opening strategy screen etc. Im running it on a mac with macOS sierra, 1.6 ghz speed and 8gb of memory.

  22. Is there a chance that coalition offers could be enabled as there has been talk of a ‘progressive alliance’ between SNP, Greens, Plaid etc. to fight the Conservatives. I know it is a bit late in the campaign but could occur in post election talks should there be a hung parliament.


  23. @Daons,

    Adding the possibility of coalitions is on the to-do list. It probably won’t be added within the next couple of weeks.

  24. @Kevin,

    Ok, my guess is it’s something specific to your system, such as another program(s) you are running. Have you checked your system info to see what your available RAM is when running the game? Also, do you have any third-party programs running that would constantly check program activity?

  25. I’ve noticed a duplicate Macron victory event at the same time as the Manchester bombing event.
