Obviously, I can only speak for myself on this but I don't personally regret the purchase of the FSX Vega. While many of the promised features haven't materialized or are incomplete there were some that were introduced that I didn't expect and have enjoyed a lot. I still fly it and have fun with it. While it was pretty basic initially, the dev did put out a number of bug fixes and new features. The most recent release from a year and a half ago (v 0.85.03?) is quite good. I'd love to see the full, Accusim-ish like levels of system/wear modeling if it were to get there. And incomplete features can be annoying. But, as-is I have an excellently modeled 3d representation of the Vega, a believable flight model, better-than-default systems and instruments modeling, and the aircraft state persists from flight to flight. Honestly I like flying it a lot more than some of the recent Asobo releases.Understandably, not everyone is going to have the same feelings I do about what was delivered vs. what was promised. But I figure it is useful to have a few different opinions out there on this one.Chris
