Heh, good read. 
Anyone that can consistently fly, fly the approach and land well Microsoft Flight Sim will have no problem flying/landing the real thing.  Granted I had a lot of time flying with my dad in his Super Cub.  But I really believe that anyone that flys well in MS Flight Sim could do it. 
I took the 737-200 Level D sim around the pattern at Hartsfield when I was 14, it flew exactly as MS Flight Sim, which I had been flying frequently.  Greased it on the numbers a few times, flew one ILS to near minimums as well.  I had basically memorized the approach from the plates I was using for MS Flight Sim, so I knew the freqs, cross-radials, fixes, headings, altitudes, etc.  I had to work the spoilers to get down on one approach though, - I don't think that's standard procedure in the final approach phase 

 - but it worked out nicely.  
On one of the climb-outs he told me to go ahead and roll it - I told him I thought we were too low & slow to get it around without stalling it on the bottom half, so I continued to climb to about 3,500, pitched up to ~45 and threw in the aileron/rudder and around it went.  On the backside we were pointed about 50* nose down with a ~60* right bank - I was pulling it a bit to get it on around and get the nose up and the stick shaker went off, I dumped the nose a bit and coaxed it on out of the dive completing the roll.  They were impressed.
