I think if everybody could get their planes of choice quickly, right now, so we were seeing 100+ connies/DC6/Bristols churned out a month, there'd be less people impatient and/or bored now, but then in 6 real life weeks with the demand now filled, they'd be bored then. And it is a GW that will last over 18 RL months, there will be stretches of boredom and/or impatience.
The only difficulty is that it's harder to start an airline right now, so if you do make mistakes and want to restart, you might get especially frustrated, it'll be easier in 4-6 RL weeks with a lot more planes available, less demand from the UM for older planes, and older planes returned to the brokers because they've been replaced or people have BKed. But it's like that in every longer world, ~2 years/2 RL weeks in is always the hardest time to get started, because all the big, aggressive airlines are still grabbing anything they can from the UM, and have not ramped up enough to have steady supply of new planes, nor to start returning their older planes.
Could go back to the staggered starts again, limit the number of people allowed to join on day one, but pretty sure that didn't work at all, leads to more frustration because if you can't get in on day one, more likely to not play. In 2 RL months starting up in the world will be easy, outside of the usual ~10 airports without slots, and still allow 18+ months, 70+ game years of building a huge airline. Right now, if you intend to have big airline and haven't gone the generic grab heaps of DC6/connies and start ordering them new path, you're stuck with being patient and/or getting creative. That'll always be the case at this point of a new world, I think. Even if it is alleviated somewhat by forcing more lines (DC4, Martin, etc in this world) to start open, and forcing more bigger options onto the UM (Breguets and first DC7 option in this game) at game start.
