I bought it on day 1 but only because it was pretty cheap. Fun little title to relax, nothing major.
But i'am afraid that a proper flight sim is too big for DTG. Seeing how CSX is a bit of a mess, unfinished, poorly optimized with weak physics i don't have high hopes for their flight simulator.
I wish them well, i hope they patch CSX, i really want to get it some day but a flight sim is a whole different ball game. It's good we have P3D and X-Plane to choose from.
