Congrats.
Mine had an irony in that I had built up well over 1000 hours before the achievements were installed. It finally tripped after another 1000 hours, I guess, because I noticed it later. I thought it was unfair that I had to reach a bigger number than other people did to get the same achievement, but then again, there was no worry I would hit whatever threshold they set, sooner or later. Addiction like this guarantees it.
