The game is good, far better then AC4 but it isn’t the reality simulator that you'd find in the top of the line sims on the computer which themselves are a bit flawed...
The graphics are better then all before, you get nice moody weather effects, nice missile trails, the afterburners have been re-work and all look the planes have been worked on with things like heavier, more authentic textures, accurate moving parts, and what looks like more polygons... The feature I like best is the vapor effect when they break the sound barrier.
Just don’t expect realistic weapons load-out, realistic real world performance like time to altitude, actual altitude levels per jet, real world top speeds with weapon and fuel, and actual acceleration times...
All in all the game is a great addition to the sierse with a good story and great arcade style game play...
