Zoso, I fly quite a few NOE missions, despite the sector counters (something I really wish is in the path of solving). I still stick to the flatness of the terrain. It has rolling hills, ok. But the canyon flying fun of 1.04 is here limited to the ridges (I think that is the right word) that divide initially the three countries.
Besides that, NOE over round hilly terrains are OK, but the real challenge are over mountains. There they are really fun.
Cheers,
Pepe.
