Game you have taken time off from work/school once it came out.

For me it was every single one of the Gran Turismo games. Skipped school, took holidays/sickies from work just to play it. You name it. When it was released i stayed up pretty much 20hrs each day except the first 2 nights where i didnt really sleep more then 1-2 hours.. lol.
