What's up, Ivan..
If you happen to be down to the last fifty bucks in your wallet, then I'd probably wait.. (until payday...)
Otherwise, buy it
It's unfinished, but it is awesome.
I play every day for about an hour, usually I am frustrated by launcher ex problems, or I get the stutters out of nowhere..and I shut it down and count to ten and find something productive to do instead..
But I still get some quality time in ..
I gotta say, the cockpits paired with TrackIR 6DOF is just cool as hell when you get the hang of it..
Look over your nose, line up deflection shots that were impossible in the previous sim..
If/when they get the land/trees etc on par with the rest of the sim..
Kiss your "waking life" goodbye, sim junkies..
