I've been around the FS world (not FSW) since 1980. So I've known of GSX for a while and was never sure it would fit in with how I like to sim. GSX Level 2 changed that for me for a couple of reasons. I own several airports and the devs of those airports are slow (or if they ever will) change the jetways to SODE or even something that MOVES! I absolutely dispise static jetways. There is a rather well known dev that so far hasn't said they will ever fix EHAM, I'm still waiting for dynamic lighting for that airport. Soooo, in 30 minutes, I had used GSXL2 and made several gates with now SODE level jetways! I like the ramp features as well, as I have used the ones that come with PMDG QotS II. It just added that to all of my none PMDG aircrafts. So all and all, I love GSXL2 and it will add to your immersion of your aircraft at an airport. If in doubt, try the demo. One thing I really appreciate about FSDT is the Demo's, it has helped make the sell for me. Who has even watched a video of what appears to be a great airport to have it suck. Try it out on your sim for the time alloted and you know. So thanks FSDT! I am super excited about the new ORD!
