Obviously I can't be specific about my experience so far, so how do I expand on my earlier post....? How about like this. Just the facts...
I'm a real life pilot so I know what flying an airplane should feel like.
I mostly prefer military flight sims when I have time for simming. When I do play FSX, I prefer low level, VFR flights in light GA aircraft, often at lower altitudes than what you would fly in real life. Sometimes I like to just practice landings. I have no interest in simulating a 747 flight from New York to London (not that there's anything wrong with doing that).
I prefer smaller scenery areas with much higher levels of detail and accuracy rather than a generic looking larger area.
I find the amount of money you need to spend on add-ons for FSX to get it to "look good" to be unacceptable. I know lots of companies make money providing those add-ons and they've done a great job, but ultimately I get those add-ons because I feel FSX fell short in those areas.
I don't ever simulate flight planning or any of that stuff (not that there's anything wrong with doing that).
At thia point, I could see myself uninstalling FSX after Flight is released. The cost and availability of addon aircraft and scenery still may affect that, though.
Sounds like Flight is perfect for your needs Malibu.
Personally I'm looking forward to trying it and it sounds like a fun diversion I will enjoy at times, but I am not a real life pilot and part of what I want in a sim is being able to do more indepth sim situations, and in real world locations where I have been or close to my home.
So as you can see it doesn't meet my needs to replace FSX, but then again it doesn't have to since I don't need to pick just one or the other, I plan to enjoy flight for the cheap simlite diversion VFR flying around Hawaii, and I will continue to enjoy FSX for more detailed sim situations and still hold hope for MS to come out with some more hardcore sim options to add to it in the future (atc, more global locations, jets etc.)
We all come at the civil sim from different perspectives and different goals, I've spent lots of money on FSX and addons but I love it, with the right add-ons FSX approaches the level of study sim with amazing scenery, I get to fly some awesome planes out of some very detailed scenery that closely models my local real world region, yes it costs some money but in the end I would spend much more on a real pilot's license, nevermind the cost of the awesome aircraft in my virtual hangar.
Still waiting for my MS Flight beta invite and looking forward to it, hopefully in the long run MS will cater to both the simlite and hardcore needs, I think the potential is there, especially once they've gotten a bunch of new gamers to try this new "airplane game" and some catch the sim bug and want more.
