Been using flight sims going all the way back to Microprose F117a on the Amiga. Pretty basic but we all have to start somewhere. I then moved through Flight Unlimited 2, FS2000, FS2004, FSX, X Plane 9 and then onto X Plane 11 when I started taking it seriously. It had taken until X Plane 11 for me to finally feel fully immersed enough. I still have a great fondness for Flight Unlimited 2 mind, There were some great adventures in that, including the Star Trek themed one with Kirk sat beside you.
