Rise of Flight - To buy or not to buy?

[Buzpilot]

I have this balloon sim, and yes, it's a balloon you fly in a 1km radius balloon, and can't spot any plane outside it.
Thats the only thing they need to fix, but i read somewhere they can't, because of the graphic engine.
Also, i tried the new 2 engine bomber, but when i used my Warthog throttle to program engine start, with 'Eng Oper' buttons, it fail to recognize the buttons after programming them in ok, and a error msg, input unreadable. needed 'Recovery' to fix that.
But exept for this ,it's a great sim , but not for real combat , turn combat where you know where to meet, is only option.
