You've obviously never played Mig Alley! Awesome game! TONNES of community updates and mods. Some still fly it today!
I have owned MiG Alley since before Rowan went under and released the source code. The BDG made a few basic patches to improve stability and add TrackIR, but it never got the improvements they did for Battle of Britain that became Battle of Britain 2. Playing MiG Alley in this day and age is like going back to Jane's games... way too old. SFP1's original Korean War addon far surpassed what I could do with MiG Alley, so I gave it up a long time ago. SF2 still has active modder development with 3d aircraft models and textures that match the best payware in many cases. The SF2 KAW (Korean Air War) mod for SF2 is extensive. You can fly carrier based missions with the F4U-4, F9F, AD2, F2H-2, etc. I personally prefer flying the F2H-2, which is a rare bird in combat flight sims. My problem with SF2 is that the core engine ceased development 10 years ago. The biggest hole in the SF2 engine was the terrain, which looked dated in 2003 (little better than MiG Alley). User mods can only do so much with texturing.
A Korean War sim with a modern graphics engine, realistic physics, VR support, dynamic campaigns and multiplayer is what I want. MiG Alley isn't it, SF2 is a lot closer, DCS World is heading in that direction, but it is amazing that MiG Alley is 20 years old yet remains the only decent, dedicated Korean War themed air combat simulator released since that time.
