Suppose you had purchased Midway and Laguardia first, before Kennedy and O'Hare, would you or would you not buy them? Your anaology is like not buying Dallas Fort Worth because you already owned Dallas Love Field.
Yeah if Midway and Laguardia had come out first then I wouldn't have purchased JFK or ORD.
Although there is a stipulation. Say Midway and Laguardia had come out first but it was by BluePrint and I had bought them a while back just to have a 3rd party airport to fly to in that area, then I would go ahead and get the FSDT version of ORD and JFK since they are higher quality and larger hubs, and the fact that I have more interest in ORD and JFK anyways.
I still have not and probably wont buy FlyTampa's Midway since it's so close to KORD. Even as much as I like FT's stuff, Midway just doesn't interest me much. Now, if FSDT had never made ORD then yes, I would buy the FT Midway just to have a nice airport in Chicago to fly to, same for KLGA.
On the KDFW and KDAL subject, I actually purchased the BluePrint KDAL about 2 years ago since there was no KDFW and the fact that since I live in Dallas I wanted to have at least one 3rd party airport for my home town. However since FSDT's KDFW came out I have since disabled it in my scenery.cfg since its not really needed anylonger as I much prefer to fly out of KDFW and the fact that I like doing AA flights which originate out of KDFW.
That's what I was thinking... He says he won't buy OAK because of SFO, MDW because of ORD. But he has FLL and might consider buying MIA...backwards comparison.
Only because KMIA is a larger hub and has more international traffic coming into and out of it and the fact that the Miami/Ft. Lauderdale area is one of my favorite places to vacation in the US and I have flown many times into and out of each hub and therefore dont mind owning each of them.
Of course the same could be said about KSFO and KOAK, one being like KFLL (KOAK) and the other being like KMIA (KSFO), but since I dont have a special fondness for San Fran, even though my dad and his side of the family are from there, it doesn't hold enough interest for me to own both SFO and OAK. I also never purchased or will purchase IS'es KSJC for the same reason, even though its not as close to KSFO, its still close enough that I dont want it.
There's really nothing to debate over my answer. The OP asked for opinions so I gave mine, which of course maybe different that other peoples decision, but there's really no need to disect my answer as its just my opinion and the fact that FSDT probably wont be making KOAK anyways.
