I never had any PC game that was actually a game. I mainly had edutainment games like Reading Blaster, Math Blaster, and Jumpstart. Which I was like 4-9 when I played these games. (Though I've been wanting to play them for the sake of playing them, but I can't find them.) I also had a slew of Humongous Entertainment games. I had two Freddi Fish games, all the Putt Putt games, one Spy Fox game, two Pajama Sam games, and Backyard Baseball, which are all fun and I have fond memories of... well I have fond memories of all of them. One other that I remember was some Tonka game, but it was lack luster and didn't keep my attention. xD
The only other games I ever got were LEGO Racing and LEGO Rock Raiders, both being awesome.
Though my favorite, for whatever reason, was a game that I would replay so much that I think I could beat it without thinking about it, and that game is Where In Time Is Carmen Sandiego. I played and replayed the heck out of it. Mainly because I loved history when I was young, and I think all the clues were different every playthrough. Though, I know I played it every chance I got. There was one day I was home sick from school and I just played that the whole day. I think I beat it twice that day. Either way, that was one of my favorite PC games.
As for games I played that I didn't own, my cousin had Roller Coaster Tycoon 2, which I got to play a little bit of and it was pretty fun. I don't think I played enough to get the full experience though. And she had the Sims 2, which I just watched her play.
Then there's the PC games we had at school. I don't remember any of them, except for one, and I'm sure everyone knows what I'm talking about before I even type it. Oregon Trail II. You could also say the first one, but I've only played the second one. It was the only time you play video games in school and get away with it. Not only that, it was actually fun. In fact, for the past week, I've been wanting to play it just for the sake of playing it, but I don't own it and I think my computer is too powerful to run it.
Though, yeah. That was the most I've ever experienced in PC gaming. I didn't even know you could play powerful games on PC until a few years ago. I thought they could only run basic edutainment games. That's also because I never looked at PC games when I went video game shopping, I would always buy console games so that could've been my fault, but it was also a time when I could only get one game every 4 or 5 months and I didn't want to waste it.
