Could have sworn I mentioned that my FS2004 install was 55GB, thus is my main Sim and why I mentioned it so that this question would not be asked.
The thing is, I have damn near every single aircraft known fly around me on schedules landing and taking off. Everything from FedEx, UPS, Airborne Express, United, Delta, Great Lakes, Frontier, Hawaiian Airlines, EVERYTHING! And I LOVE my RealityXP gauges that look and function like the real-life counter parts. I have them all, I'm a gaugeoholic. I would have to buy them for FSX and some don't exist in FSX as they do in FS2004. Love my gauges's. I do fly using SID and STARS, the whole damn nine yards. Even played in VATSIM.
Would you believe I picked up a yoke and pedals for a grand total of $20 bucks at a yard sale? HAHAHA When I payed, the guy said, "glad that's gone." I was like, 'your very welcome dude.' They only go for a couple hundred on ebay.
Anyway, I do want to buy the PMDG 737NGX for FSX as it has more bells and whistles than the PMDG 737NG in FS2004. I guess I could convert my current crop of AI aircraft so that they could fly in FSX. Turbo props are iffy though. But I did make Area-51 in FS2004 which was a few years long project for me and I'm still not done with it. It uses real Sat imagery and the buildings are placed to look as close to the real KXTA as possible. I even made ground call themselves Kelly Johnson ground when communicating with aircraft. I just wish I could program the game so that the F-16's parked there would take off and intercept trespassers. LOL!
