I have played sims and this is a sim, Janes has done it again. The flight model is extremely impressive, you are allways on alert and sometime need more thne two hands to keep all flight systems checked, so it will take time to master it, thats why F-15 is so realistic. The desert terraine is bland on your average video card, though very remarkable on some Voodoo5 card. The terrained also stays interesting through out flight with changing effects and good weather effects, though I never seem to get rain, maybe cause I am flying at 600kts. Just about every button on the flight deck has a purpose and each weaopon has a seperate package of buttons and data screens to accompany it.
Sound is like it sohuld be.
The aircrafts engines, the basic missile launches and your fellow pilots and wingmen communicating with you. You won't hear some loud push if you put on your afterburners, you will just go faster, like the F-15 in reality. You won't hear the cannons, because in relaity, the F-15 goes so fast and has such a strong canopy, cannons can't be heard, you will hear the internal mechanics working the gun with a low volume tapping sound, like real life. Janes F-15 is so deatailed you can just about smell the engine exhaust. So I was quite pleasanly surprised with my immidiate instant results with my basic Celeron 366 Mhz.
