From Crunchy's post it doesn't sound like overly realistic flight physics. If it would have physics at least comparable to warbirds that could probably lure me in.

There is several levels of realism that you can play in War Thunder.

On Full Realism Battles people say that they can't even get their planes from the ground (I didn't even try, I play arcade and having great fun).

Today the game went into Global Open Beta, so nothing costs you to try it yourself. Even on arcade difficulty the game "feels" more "real" than many so-called WW2 simulators.
