About 1998, I played the demo for the first Fallout, I had "heard good things" the typical motivator for trying out brand spanking new cRPGs. I really liked the demo, and had images and scenarios from it stuck in my head whenever I'd venture near other isometric games for a good year before I actually picked up Fallout 1 and 2.
1999, there was a Computer Convention thingy around New Jersey and they had a crapton of cheap games, hardware, and whatnot.
The best thing they had however, was a gaming stall that had a ton of sealed older games for dirt cheap, Fallout was one of them, big box and everything. Fallout 2 also happened to be there, although I picked that one up at a different stall since it wasn't that old at that point yet (It came out at the end of 1998 and it was early 1999).
Obviously I bought them both, I also brought home Sid Meier's Alpha Centauri, a copy of Half-Life and Baldur's Gate (which I hadn't played yet).
This was obviously one the greatest hauls I ever had, and everything was fucking cheap, Fallout 1 was a measly $15, Fallout 2 was $30, Alpha Centauri only $10 (Holy shit, best deal ever) with Half-Life and Baldur's Gate being the most expensive at around $40 each. Great, great stuff.
Came home, first game I played was Baldur's Gate because it had immense hype and because I was more into RPGs than shooters (especially back then). I was satisfied by that, got up to Nashkel and played around thirty minutes a day, it took me around five months to beat the game with the amount of time I put into it, I never did consider it a "sit down and play for hours" kind of deal, although the sequel changed that.
I ran through the other games and eventually came to the original Fallout.
I beat that in two days, two god damn days of playing nothing but Fallout. This was my first time playing, so I hadn't been jaded by the bugs and issues that now plague me each time I play it as obvious detractors. Nah, back then it was shiny-new-game-syndrome and everything was freaking perfect.
Cue me going nuts about it and telling everyone at school, playing through it with practically every kind of character and doing so with the sequel in kind.
It was a great experience.
Although I think I'm understating the other games, I went the same way about Alpha Centauri and I still think that game is freaking beautiful.
