Hey I remember you BT guys from back then. I flew with 13th TAS and Assassins that year you quit I think.
2 things.
1. Get yourself a bike, it's summer man!
2. Dust off that stick like you said and give AH a go now if you have the means, and ignore the community stuff. Best thing you can do coming back IMO is detune 200 for the first few months you're back, then you won't need to worry very much about the viper-like qualities some of said "community" has adopted. I can completely relate to a lot of the things you said in your OP, and this game is still fantastic and still without peer. I've found that FSO has been what's kept me going this year when I can make it, and if you want to give that a whirl friday nights PM me or anybody in the FSO forums and you'll be able to get hooked up with a squad that will help you get back on the scenario horse. Friday nights here are a complete blast, and a lot of players but in a LOT of hard work to make squad ops a good time, and it shows.
Congrats on how life has turned out for you 10 years later, take some of that success and spend the 15$, which is still a crazy value, and you are from a time when the game cost 30$ (it was 55$ here in Canada after the dollar converted out back then), so I bet you appreciate the price more, as I do. Come fly the sort of friendly skies, I doubt you'll regret it.
