Both are flying sims, one is a ww2 dogfighting game and the other is a falklands/malvinas conflict based game (avec jets). Both look extremely promising to me, flying game freak, and am awaiting their release with impatience.

If you like flying games yourself, I recommend Air Attack, an old ww2 flying game with a tight fun community, and it's free. Awesome game.
The game can be found at http://www.team-airattack.de , look around to find out how to get flying.
There's also https://fighterace.ketsujin.com/ , which isn't free but is a blast anyway, albeit with a steep learning curve.
And then, of course, there's Aces High, two week trial at http://www.hitechcreations.com/
