When I was first learning to fly, I used to go home after each lesson and refly it as near as I could remember on Microsoft Flight Sim 95. Effects of controls, straight and level etc etc. Even these days I sometimes pull out a more modern version to practice some things, particlarly instrument flight. However, it never replaces the real thing and really is just a bit of educational fun.
A friend of mine built a B737 sim cockpit in his garage and that is a different experience altogether. Still no "feel" but visually it looks fantastic and we "flew" IFR across the USA, complete with traffic and live ATC, as well as did the Sydney to Melbourne route a few times. Good fun, great experience, just don't get too caught up in thinking that it is real.
