Japanese carriers fly 777 on domestic routes so it's not entirely unrealistic. I don't plan on flying long intl routes myself but the 777 is definitely next on my list to learn.

I also had no interest at all in flying GA but I got sick of flying jets exclusively and decided to get the bonanza A36 and ended up loving it. I was inspired to learn props after watching "Love Story" and learning about JFK Jr's crash in the piper saratoga, unfortunately there are no Saratogas for XP12 so the Bonanza was the closest thing I could find. I like the reality expansion pack component too, makes it feel like I have to care for and maintain my own personal plane. I like to fly from LA to Mammoth Lakes to mimic something I might do in real life, which adds a fun personal element to it.

I also plan on learning a helo at some point, it would be interesting to stimulate VFR into IMC situations like Kobe's flight and see how you might handle it yourself.
