Thank you very much. Downloading and trying the first mission right now :)
EDIT: I tried the very first mission and I liked it. I find that it increases the immersion, even if I would have liked to have more alternatives while chatting with my wingman: in some occasions, in fact, I had only once choice, so I felt forced to continue speaking with the only one available option to see where it all was going to end.
With this premise, technically I met two problems, I dunno if they depend on me or from the mission itself:
1) sometimes subtitles appeared twice while chatting. That's something that never happens in other mission, both in single or multi player mode;
2) I landed succesfully in Kobuleti (by the way, nice surprise at the end of the runway), did all the taxy out, arrived to the parking zone and did even a system off of the aircraft to increase the realism of the situation, but, when I quit, I received a message about me not completing the goals and thus failing the campaign.
