The only flight "simulator" for modern air combat I know is Falcon 4.0, even Lock-on is more or less arcade in its own way (being able to land a sukhoi on a carrier right from the first attempt ever cannot be realistic, and so on). Flying correctly the F16 in F4.0 is already a lot of work, and since when the editor opened the code to the community some people made most of its systems at least usable, you can use the real checklists etc (you can in F4.0 but IIRC you just skip a few items like the pressurisation system or stuff like that). The only downside is that being a very old game, the flight enveloppe doesn't feel 100% realistic, although a modern fighter is nothing else than a brick with big engines to keep it and its load in the air, so it's not like it's gonna impact on the overall experience.
Otherwise on the semi-arcade side, IL2 is cool to have some fun with. I had a lot of fun with Microsoft Combat Simulator too, back in the days, it's an underrated game. Ace combat is 100% arcade, I don't even know why it's called "simulation"
. On the first video the plane doesn't even bank enough to be able to have such a turn rate, or does moves that are impossible for a plane to do, I know I'm obviously picky about these things but damn it's frustrating it's like they didn't even care about asking someone who knows a bit of aerodynamics if at least it looks normal. In ace combat 2 or 3 some planes had their surfaces moving in the wrong direction, I mean wtf, the designers only think about the eye candy side of things. I always had fun with them though overall, as long as you take them for a shot em up with aircraft basically. What's the deal with this semi autopilot for dogfight in the last version ?
