That’s very unfavorable argument and a negative and short sighted way of looking at things.
Adding extensive customization is the focal point of some well known games and it’s something game studios take pride in being able to offer. It’s also commonly advertised as how one of the many ways a certain game can accommodate gamers and PC’s of any level.
If there’s one game which can highly benefit from adding more customization and settings options, it’s a flight sim.
People all have different tastes, different preferences, different likes and dislikes, different levels of hardware availabilities.
Adding settings is probably the easiest way to battle the negative crowd. If you don’t like something, just turn the slider this way and you’re good to go.
Asobo has made a flight sim using groundbreaking technologies and AI’s on a 1:1 representation of the earth. That last point alone is enough to impress any other non-sim type gamer. They’ve already literally conquered the world. So I’m pretty sure adding adjustment sliders and more settings into MSFS can only be better for the sim, not worse.
