I have been starting a Night bombing campaign in the newly released Halifax, with all the latest knick knacks, and I can honestly say, The first few missions are very good, and are problem free, (I wish I had my screenshots to post, but alas, I don't) however, I was wondering what people's opinions are on a campaign that, to be entirely honest, is rather repetitive? And second, how long should the missions be? All opinions and questions are welcom, as I'm trying to make this campaign be best suited to the people who will play it.
