First PC game I saw was probably mid 80's, my buddies older brother was absolutely hooked on this submarine game.
He'd literally sit for days in a little basement room hunting convoys, and we'd check in every now and then to bullshit with him and watch his progress.
"Yeah, I'm about 900 miles south west of the Azores now, in about 9 hours I should have them in my sights ,,, Wanna stay and watch ??"
Uh, thanks, but no thanks. Graphics were pure shit, even by 80's standards. Most of it was just numbers and bearings, if he popped up to have a look above the sea, you'd really have to stretch your imagination to see anything resembling a sub cruising on the surface. [The guy, Jerry, was a glue sniffer, tried to get everyone else to sniff. "No thanks dude, I know what it smells like", I'd tell him. Laid him back, and he was heavily addicted. Died of a brain hemorrhage some years later].
When Nintendo & Turbo game out, things picked up dramatically, but I joined the service for an 8 year hitch around that time, so missed out on much of the early action. When I was able to get a system, I went with Turbo, and happily played and built up my game inventory for a couple of years ... But when Windows 95 came out, things changed.
I got it around 97, and got Battlezone, and that game blew me away. Incredible graphics, and a control system that I have never seen before, or since.
I still play it, and it still looks great skimming over the moon, and leading battle squadrons against the enemy. After a dose of that, I pretty much put the turbo away as childs play, until I had kids old enough to play it. [Still was very protective of my Turbo, and made sure they didn't abuse it. I banned one of my sons from Turbo for a whole year when he got pissed and slammed the control pad on the ground].
Never really looked back, I think PC games are far superior to consoles in almost all respects. Although my kids ended up with just about every gaming system that came out, I never got into them. That said, I'm not exactly a PC game addict. I still have many stashed away in the attic that I never even opened, and the majority of games I'd play and lose interest quickly. I have probably well over 100 old PC games, boxes and all, stashed away, many more that were downloaded and saved to CD. Haven't looked at them in years. I can count on both hands the numbers of games that I seriously got into.
Aside for Battlezone, my all time favorite, they include:
System Shock 2
Far Cry
Total Annihilation
And a few others that I can't even think of their names. One was a hot chick named Rhen flying around on a dragon.
The only game I play now and have been playing for years, and the only game I have ever played online, is Dawn of War Dark Crusade, an incredible base building race war game.
