So it looks like iOS 8 is forcing some of my games that were originally designed for Landscape mode  into Portrait mode.  Games affecter are Train Sim, Train Sim Lite, Car Crashers & Kids Plane Racers.

There is an easy fix and I have submitted  a new version of these games to the iTunes store, however I am sure there are many developers in the same boat trying to fix their apps/games now that iOS is live and the reviewers are probably overwhelmed.

On the positive side, most of the games actually work quite well in Portrait mode with the exception of Kids Plane Racers, so it could be worse.

So thanks Apple, I love your products but stop breaking stuff.
