because for teenage boys shooting things and blowing stuff up is a lot more fun over the long hall
For the long hall, you'll need to haul the sniper rifle with you. For the short hall, a shotgun or assault rifle will do.
Speaking as someone who was a teenaged boy when Myst came out, I can honestly say no game interested me less than it did. I saw demos of it at the video game stores, and all the clerks would gush over it being amazing, groundbreaking, etc. I'd nod my head, say "okay dude, yeah, do you even know what you're talking about?" and go home to play Ultima VII. To me it looked like the Sierra * Quest games without the things that made those games fun.
The game that I believe was the most influential from that period in time was Wolfenstein 3D, which was the seminal FPS game in my opinion. As a shareware game, it reached an audience of "anyone who had a modem and the number of a BBS with a halfway-decent files section." It was over the top, just a bit camp, and a thousand percent fun. You can even play it on Facebook now. I got banned from my high school computer network for installing Wolf3D on the server. A teacher walked in and our entire Turbo Pascal class was slaying Nazis. My only defense was that it was more useful than learning Pascal. They were not amused.
I agree with the parent poster that the attributes of FPS games are very alluring to teenaged boys, but I wouldn't necessarily consider that a bad thing (or a good thing, either). It is what it is.
