Anectodally the internet was reliable, fast as hell, and there was a vast world to explore for me in the 90's. And I'm not talking just text downloads. And certainly not referring to 28.8k modems. 56k was ok, shotgun 56k was better. I went pro in CS once I got ADSl and I dearly miss client side registration because it was so damn reliable and snappy with rarely any desync problems.
Back then it was very easy to just aim further ahead of your moving target with the distance being proportional to your ping. I distincly remember playing kingpin and quake in a hotel room once and I had a 250 ping. All I did was prefire way early or in the case of the long range shots.. Oh god it was so satisfying to lead them by a few extra "feet", click, sit back and then after what seemed like forever I'd hear that thump thump thump of the rifle and they'd drop. You simply can't do that these days with reliability. You play against jerks on VPNs from AU who warp 20 feet before shooting you.
I don't mean to say you're wrong, but I thought you might find it interesting. I was just a dumb kid but we downloaded stuff and had small 5-man lan parties where we played online too since we didnt have enough for balanced matches. It wasn't bad at all and we didn't even have a proper hub until much later on.
Nowdays every realtime app suffers it seems. No matter where I'm at. And if you go to a big regional lan party everyone is queueing online. No local servers, or if there are it's kinda dead or it's private hard core competitive games, which I do love, but I miss the goofing off and socializing in lan servers too. The changes for me have been less than ideal, as a pro gamer and just regular gamer.
Also as a UX/UI dev I've noticed things have become.. Annoying as hell to use. Even intentionally thanks to questionable business practices.
Today I can plan my day online in 20minutes or less. Back in the day it wasn't too easy for me I wasn't the best student.
Sorry for the novel. Thanks for sharing.
