Not that it has anything to do with anything, but I soloed in ultralights in 1.5 hours, mainly because of the familiarity I had with flight sims. As Toad mentioned, the landing pattern and the look of the approach was the only thing that really presented anything approaching a problem, and after a circuit or two, it wasn't a prob. I've since flown light aircraft with similar results (no, I don't have my license).
Creamo and Easymo have a point WRT systems and views in a way... I really do like the views offered by sims like WWIIOL or Il-2. It's always a bit disjointing to come back and play AH and remember I have a straight-six view. It's also interesting to go on autopilot once in a while and watch the controls work inflight (Il-2), especially landing pattern. Of the three mentioned sims, none give me the feeling of leaning forward in the cockpit of a taildragger sitting on the ground like Il-2. Nuances like that are interesting and give sims flavor.
AH is AH, Il-2 is Il-2, and the rest are what they are. If stuff is added to make AH more complex I will like it or not. In the end, there are plenty of options for me to take to get my thrill for simulation.
