Why no plans for a third Thrillville? My kids' can't get enough of the first two, and I'm starting to get addicted myself. Everyone who I know that has played either of the first two games loves it. I would be stunned if there wasn't a market for a third installment.
When you do make a third instalment, I disagree that there should be no power meter, but I do think that the parks should have more power allowed per section OR maybe as part of the research budget one of the things that should be researched is getting additional power OR maybe one of the mission rewards could be to earn extra power.
