Don't remember why. I probably didn't understand it.
Your moral justification is totally reasonable.

I like to reminisce about games. Care to join me?

First flight sim, F-15 Strike Eagle, on 5+1/4 floppies.

A few years later I bought a Microsoft "Sidewinder" joystick just for flight sims. It came with "MechWarrior". I played the whole series but enjoyed the original the most. There was a layer of strategy because you could command a handful of other mechs and send them into ambush positions. The Mech games that came out later were rigidly linear. Only one way to do things.

The "Sims". I had to quit playing because I'd get up every morning, brush my teeth, shower and get ready for work. I started to feel like a Sim myself. Too much reality.

I loved "Sim City" and a few years ago I bought Sim City 3000. I took it off my gaming computer but luckily saved my city files because I now have an urge to play it.

“A-10 Cuba” was a satisfying flight sim even though the graphics were a little blocky (it may have been video card at the time). You had to spend a lot of time on the bombing range to get the hang of the bombsights. And if you didn’t take out the runways in time, the Migs would take off and you’d be screwed. The A10 wasn’t a dogfighter.

“Mig Alley” was one of my all-time favorites. F-86 Sabre vs. the Mig 15. Very realistic dog fighting. The planes capabilities were accurately modeled as to rate of clime and speed at altitude. It wasn’t easy. You had to deal with red-outs, black-outs, buffeting, sun blindness ect. The Sidewinder joystick let you “feel” the buffeting in your hand, it shook fairly violently.
You used guns, not guided missles and your ammo was limited to 300 (?) shots. One thing that added to the flavor of the game was the com chatter between you and your other pilots. On your “6” becomes a frequent phrase. It was made for Widows 98 but there were patches to run it on XP. I never had much luck with them.

And then there’s Half-Life. A series that immerses you in a Sci-Fi story complete with technologies ranging from the “gravity gun” down to a trusty crowbar. Scary mutants and monsters and lots of blood and gore. Each level was a unique challenge and culminated with a puzzle almost worthy of being a brain teaser. Sound effects added a high level of realism, sometime too real.
I just learned yesterday that the original Half-Life remake was released late last year. It's been modernized complete with much better graphics. For years there were reports that it was in the works but after a short time it earned the title of “Vaporware”. It’s called It’s called “Black Mesa” , after the New Mexico research lab where the first game takes place.

Looks like I need to build another computer to play it. Oh darn….
