FSX/P3D. One thing I really wish P3D had is missions and expansions. For this, I trun to FSX Steam Edition for the extra fun. Iris Simulations is developing the Extra 330SC stunt aircraft accurately modeled down to the finest details including a fully functional cockpit with authentic audio and great flight modelling. Skychaser will launch exclusively via Steam for £14.99 or will be sold together with Microsoft FSX: Steam Edition for £29.99.
