I have to say that since the latest beta I am very happy with Aerofly FS 2. Specially the additions to the Q400 FMS and the fact that you can now truly set it up cold and dark (and by that I mean editing the main.mcf so it is cold and dark right after loading) has tipped me over the point of no return. And by that I mean that if you want to find files relating to other civil flightsims in my home as of today you will have to open up a drawer and dig for some external hard disks with archived old software because that is where my other sim files have been moved to now. The only item related to those other sims that's still on my desk is the checklist I made in the past for the Majestic Q400 because I can use 95% of it right now for the Q400 in AFS2.
I am not saying AFS2 is THE sim to get for everyone but that it is THE sim for my current use. It's very personal, of course. It's far from perfect (as I said it just tipped me over) and lacks quite a few things but what it offers right now is what I want from a flightsim nowadays. The one and only thing I really do miss is weather... and I'm also looking forward to the upcoming ATC but for my current use AFS2 is THE sim. The fact that Orbx's TE GB is coming up and an Arrow with a GNS also helps here.
Looking forward to whatever else will be coming to AFS2!
