I prefer sims without canned missions. This STS one doesnt bother me as its the historical recreation thats the fun bit, but for a jetfighter sim I really want to have more than just flying frozen missions. I want to be able tos et up waypoint attacks like Tornado, choose targets and bombs like EF2000, have a set of pilots at the base to manage like Gunship 2000, and have at least some kind of dynamic or semi dynamic campaign like all of the above and of course Falcon 4 and TAW, my favourites. Microprose did some great sims in its time, about time these new developers learned what makes up a good sim. For me technological/flight accuracy and good graphics only make up a small part of the immersion in a game. I like to feel like I am playing the game the way I want to rather than the way the developer wants me to. There are precious few sim games around like that these days. In fact can't name even one from the last ten years - except for BOB: Wings of Valour possibly which again was based on a much older game by Rowan. Last games I played like that was the superb B17 Flying Fortress and Falcon 4, havent seen anything of note come out since those. Pretty sad I think.
