When I brought half life 2 there was a lag of about 2-4 years before I could play it for the first time - I didn't read the fine print, and on a dial up connection I couldn't get past the steam client updating in a reasonable amount of time, mind you I was able to download much larger Linux ISOs over time frames of a month+ through resumable downloads.
Not really an issue these days but it certainly was back in the day
