I've gotten away from modern flight sims over the last several years, they just hold less and less fascination for me. WWII & Korea is where it's at in Steve's Dungeon, and tho I have several WWII & Korean War sims only one comes to the forefront.
I can
DEFINATELY recommend
IL-2. I haven't picked up
Forgotten Battles yet, (it's a whole new stand-alone game, not an expansion
) but if it's an "improved"
IL-2 game engine, it can't get much much better.
Having never flown any of these birds myself, I can't comment on aerodynamic accuracy. But the flight characteristics are quite singular for each aircraft, (In realistic mode, you best better know how to fly for real if you want to survive!) and the graphics are WAY-COOL,
VERY well done, indeed. Things like paint schemes are rather faithfully reproduced, the maps (terrain) are well done (except at very low-level) and the cockpits are astounding, especially in free-view.
In
IL-2 you can move your view around freely with the mouse (Are other sims like this? First I've run across it...) and re-center with a tap on the keyboard. Takes some time to master, but it's worth it. Much easier to track a foe in a dogfight this way, for me anyhow.
If you're into multi-player online gaming, you can very easily modify existing or create new paint schemes for any aircraft that is available to fly in
IL-2. (These are called skins in the gaming community) I've managed to make a couple custom skins, but I cannot get online to play. Having mucho-trouble with connecting.
(I guess for now I'll have to stick to MOH!)
IL-2 Forgotten Battles gives you many new aircraft to fly, including alotta US & Brit birds as well as a few surprises. This feature alone ensures that I'll pick it up someday; but, 'til then, the original game will more than suffice.
Here's some links for IL-2-related sites:
http://www.il2sturmovik.com/ (The official site)
http://www.flugzeugwerk.net/ (An excellent site for skins, mods and alotta other stuff, including custom-flyable aircraft)
http://www.nnavirex.com/ (Another excellent site for skins and mods, in French, but with English available)
For pure fun and enjoyment, consider these as well: Any of the
Microsoft Combat Flight Sims,
MiG Alley, almost anything
Janes and, a most unlikely suspect for a modern flight sim,
Operation Flashpoint.
OFP hasn't a true flight sim quality, it's basically a first person shooter (FPS) that gives the player the ability to fly a few aircraft (including helos) and drive many vehicles. The flight controls aren't very complicated or "realistic" in employment, but there is a realistic "feel" to it all. Some of the flyables; Mi-24, Mi-8, AH-1, AH-64, OH-56, Su-25 & A-10. There are also others, just can't recall them. I would recommend OFP only if you want to delve into the world of FPS, though, as that's the main thrust of the game.
Fade to Black...
