My opinion of course but, Fans of OFF BH&H or WWI aviation. If you were thinking that maybe you were not interested in the HITR add-on because the planes in the pack were of no particular interest to you, well there might have been a couple guys out there, you should know that HITR is so much more. Honest to goodness improvements are made to so many areas to enhance the WWI air combat experience that if you have OFF BH&H you simply need to have HITR. The HITR add-on is value packed. The devs. seem to be in a relentless pursuit of excellence and continuosly raise the bar for this genre. Feedback from current OFF pilots have been taken into account and many "wishes" have been granted. Do yourself a favor and order yours as soon as you are able.
I was the one that pushed for the D.VIII in OFF. The one computer that I have Win XP on the power supply went, my other has Win7 and I had issue with OFF on it.
I know the developers don't make much money on this but the 3 downloads for $20 are not sufficient. 1st download was deleted due to suspected corruption. The airplanes jittered and twitched unrealistically which was explained as 'wind effects'. 2nd download went...???? Got tired of messing with program and download 1st time around so just deleted everything associated with it never to waste my time on it again!
