First off, I’ll start by saying that I’m not against the rework of this. In fact, we are all for it! If I didn’t want it, I would’ve not posted and moved on ;)
The vast majority of liveries in the 737 family are from pretty well known airlines. The reason little known airlines are added is that they may be crucial for a region and you don’t know it, which gives opportunities to fly routes that are either lifelines, or just interesting in general. I would only consider 11 out of the 78 commercial 737 liveries not very well known. I personally think that’s not “too many” but that’s you thinking what you think.
I can’t really contest that. I do agree that many iconic airliners are being left out and that’s a sad sight to see. The 747 is basically unflyable unless you, say, put trim to 60, like said above or use flaps, which is unrealistic and disappointing for an airliner that you’d have a large expectation for, knowing how iconic it is. The reason smaller aircraft are added is that the minority can enjoy what they like too. Some people might not like large airliners and that’s the case with Regional props and jets by the likes of the Q400 and CRJ; they were made so that the sim can cater to as many as possible. :^)
The fact that we can express opinions is great, that’s the joy of this forum. I apologise if I sound hostile but I just want to add my $0.02 about what you’ve spoken about.
