Member since 24 July 2004 here. Doesn't feel like 20 years, but it's also hard to imagine having ~5Tb of installed games across multiple launchers just... available. Plus emulators and other resources. Steam was a pain in the arse at first, but they made it work, and they saw beyond the limitations of dialup tech. I was all for it at the time because I had one of the few Coax connections (NTL at the time, later taken over by Virgin Media) which at that point I believe was 10Mbit... Of course, nowadays we have Gigabit FTTP rolling out throughout the UK, so this seems really quaint, but it's pleasing to see how far we've come.
The US coverage still sucks. Sort your shit out guys, you're 20 years behind the UK, and we're a good 10 behind Norway, Hong Kong and others thanks to Twatcher.
