Last month, I had my first character survive the Battle. It is brilliant because I ended up being transferred up North and you get to fly that flight; whilst I knew that this was effectively 'game over', I actually found myself enjoying the flight and relieved that "I" and the other flight members were coming out of the fighting and would survive (for now at least, the Circuses of 1941 being yet to come of course
Other sims out there don't make me glad to get away from the action*, and again, brilliantly this reflects some of the real Battle of Britain accounts I've read where pilots at first were keen for action (as I feel when in the convoy battle stage) but ultimately ended up tired and seeking a break whether from relocation or just a couple of days of bad weather (again an option in this sim whether you fly or not).
I am pleased but also slightly bewildered that it takes people working on such an old game engine bringing it up to date as best they can to provide the closest thing to the kind of sim I've always wanted. It's not perfect, but it so often meets my entertainment expectations perfectly.
* I would like the option of transferring squadron, be it at the point of being 'retired' from the fight or at general request at any time, as I've read a few times from pIlots that they would make requests or get strings pulled to get into the action or be brought over to different squadrons by their old leders who were promoted elsewhere etc.
