FSX/P3D. And I would be lying if I said I wasn't impressed with what I see thus far. many of the things I have been whinning about what XPlane10 lacks appears to have been addressed in the upcoming XPlane11. That said, global seasonal variations have not appeared in the trailer. I have always wanted to like XPlane but it has always managed to keep it at bay. I do not see this by any means as a replacement to Prepar3D but as perhaps a future supplemental platform. Lest we forget, Dovetail should be making some kind of announcement soon as I recall their full fat sim is or was supposed to be due this month. Thoughts? I am for one looking forward to seeing what XP11 has to offer. Thanks to Jordan King for the tipoff!
