First combat sim was the original Falcon in the fall of 1987. I remember getting it and reading the instruction book cover to cover over the weekend. (Yeah, I know this dates me.) About a year or so later, I trued Sublogic's jet, thinking it was way more advanced because the framerate was much smoother. At the time, I flew using a keyboard - first joystick was CH's Flightstick about 2 years later. The idea of being freed from the keys (if only for just pitch & roll) was incredible. By then, I got my copy of "Their Finest Hour" - graphics was CGA at the time. I remember wondering why some planes burned and others actually exploded.
Around the time I got TFH, there actually was a television miniseries about the battle of Britain - "Piece of Cake" on Masterpiece Theater. One of the pilots loses power because his Spit still has wooden props. I'm thinking - okay, he can glide just like the Spitfires on TFH.
Those were the first and - for a while - the last sims I could get into. More sims used VGA and soon became demanding in other ways. Though I did get a VGA card in '92, the onslaught of games with even higher system requirements meant I either needed a new system or would have fewer trips to Software Etc. Falcon 3.0 was pretty much the nail in the coffin - it did run on my system (a 286) but barely. I had hoped to make Secret Weapons of the Luftwaffe run, but it do was unplayable.
My next new computer was a Pentium 166mmx in '97. The first thing I did was buy a lot of older games - "Aces of the Pacific", "X Wing" & Hind. those were either great years to get into sims or bad ones. It was easy to find not-so-old games for real cheap - like a bundle containing Falcon 3, Fleet Defender, Gunship 2000 and one other game in one box that Software Etc sold for about a dollar, or one that had Hornet 3.0, Flight Unlimited and a couple of others in a budget CD-Game section of a "99 cents or less" store. By then I had little time for sims. I'd look at these games and remember how much gameplay I squeezed out of TFH or Falcon and wonder where these games had been...
