Oh yeah. Flashback to the 90s: I got Q3Test with some magazine's cover CD and had barely-56k internet at the time so couldn't play FPSes at home until CS got popular, but that didn't matter - I was too busy wandering around the included level with my jaw on the desk.
i was downloading the test with my 33.6k modem. back then, in germany, flatrates where not yet common, so i did not want to fall in the trap and waste alot of money playing online.
i remember that some phone provider was having a "free internet" day (you could dial in for free if you where able to get one of the limited spots) and i was up 5 in the morning before school to play a free round of quake 3 test... good times.
