One thing you will find about this particular "game" is that you may join for the flight model but you will stay for the people.
This isn't a typical game, it's a community, many of us have known each other through kids and grand kids.
Try the two week trial, that will give you a taste of the flight model, but pay attention to the people in the game and that's what is going to make it stick.
Go in with no expectations, and you won't be disappointed, it's a completely different thing that just another flight sim. And don't mind the crazy ones in the attic, all families have them, just smile at them and bless their little pointy heads.
