The first flight sim I bought was A10 cuba, and even having bought just about every other flight sim that has come out over the last ten years or so, I keep going back to this.
The basic reason is that it combined a realistic flight model, with some interesting and challenging terrain to fly through. I mean the stuff like bridges, canyons, tunnels and caverns. Once I had played all the missions, it became much more interesting trying to fly through the road tunnel at maximum speed, or trying to skim throught the canyons as low as possible, it was really fun. Despite the main game being as realistic as possible, ie a sensible map of cuba with realisic combat, the developers werent afraid to just go out and have some FUN in other aspects of the game. For example the multiplayer maps included one that was covered in strange alien impossible tower structures, and one in "outer space" where you could land in floating asteroids.
"Fun" terrain, rather than eye candy is something that practically every other flight sim I can think of has done astoundingly badly.
I figure you guys are kind of limited to the Falklands terrain for the main part of the game, hey thats not a bad thing, in fact I have always been interested in seeing a Falklands based flight sim.
Can I just encourage you guys to consider doing some fun stuff in addition to the main game? Like inlcude a training map or multiplayer map covered in canyons and tunnels.
I have been longning to see a realistic harrier flight sim for so long, but it would be so much more interesting to have some crazy terrain to fly it through. In fact how about an Airwolf style 'volcano' to try and land in? Or at least a cave or two..
Just wanted to throw out some thoughts anyway, I while I appreciate hardcore flight simming I think some developers just tend to forget about the fun part at the end, perhaps this is why the flight sim market has almost ceased to exist.
