Fair enough? You think its fair that they took your money in exchange for a product that is not yet done? This practice didn't exist 10 years ago. But now companies think its ok to make paying customers part of their beta program. Fair would be letting me try a demo before making up my mind on weather or not I wanted to exchange money for the product. This practice should be illegal and I think many feel the same.
Difference is this is far more complex than other "games" that come out and it's more of a platform for the next 10 years. Nothing about it is really "game breaking". The world, sim, weather, scenery, airports, everything works minus a few minor issues I've come across. Just because a few features on the airliners are not study level (if you were expecting this, then this is unrealistic) and there are a few bugs with certain aircraft only doesn't mean it's a beta product - I mean I can see why you would think that if they were the only planes you use. I have almost zero issues while flying GA aircraft, yes some of the airliners have issues but these have far more complexity/systems and the base aircrafts are far better than what you get in other sims. Most of the issues can be worked around - I've flown plenty of long haul flights with the 787 10hrs+ and numerous smaller flights with the A320neo.
I suppose I'm being a bit more accepting of this because this is such an ambitious undertaking, and with the pandemic it's been even more difficult to develop games than it already is which I'm sure can be attributed to the issues. I've watched numerous videos with the developers, Q&A streams and it's obvious the developers are passionate about this so I'm confident the issues will be fixed over time.
