My internet provider in the early 90s maintained a Unix system with pine and lynx; it only allowed access to WWW a few months after we subscribed to their dial-up. I didn't know what to do with that remote system, but I knew `cd` and `ls`, so I looked around. Somewhere on the filesystem, I found a Hexen (IIRC) demo, and decided to download it via Kermit (the only tool/protocol I knew how to use). It took almost a day to finish, but in the end it ran - I was overjoyed. I somehow even found a cheat code for all weapons, and spent a few weeks playing the first 2 levels, while occasionally poking around in the remote system. Then the phone bill came - for 7x more than normal, on top of the ISP subscription - and I lost access to both the Internet and the computer for more than a month. Needless to say, I learned to watch that connection timer like a hawk, and it served me well for the next 10 years before broadband connection was available.

Hexen was worth it tho, good taste!
