If you really want to freshen the game up, I suggest getting a 3D projector. I lost interest in the Flight Sims for a few years, but now with a 106" 3D setup (and now there are better scenery packs), I'm going to be setting up some cool 3D stuff.
Flying in the mountains in 3D with the right scenery pack on a projector cannot be beat, it GETS very CLOSE to the real thing.
For those that can afford to do it (actually it's not nearly as expensive as people think), you can get setup for under $800 on the lowest budgets with 720p 3D. I actually fly in 1080p/24hz and 720p too (well I haven't decided for sure what my final res will be). I've mostly been playing fS 2004 because I lost my FSX disk to reinstall, but a new one is coming on Friday.
I now have to figure what all the best scenery packs are, I have budgeted about $200 for scenery packs, so we'll see how it works out.
I will say this, 3D not only makes it much more realistic, but it also increases the perceivable quality of textures, because 3D has an intrinsic anti-aliasing effect to it that is much stronger than normal algorithms. In the end, graphics look better in 3D and it's far more immersive and realistic.
