games that you realize you've been playing for 8 hours
and think "that's not too bad" and keep going.
I played
Ultima 3 so much my parents once considered taking it away becaues I didn't want to leave the house. I was probably 8 or so at the time.
But,
Kyrandia 2: Hand of fate was probably the first game that I ever played until I went to sleep, then woke up, resumed playing until I went to sleep again.
But of all games ever,
WoW has probably consumed the greatest total number of hours of my life. I had one character with something like 120 days /played. That's not "I played for 120 days." That's 24 hours * 120 days = 2880 hours of gameplay. One character. And I had several character. None with that much play time on them, but having never added up all my individual character's /played times together, I'd guess my total WoW playtime was probably fairly close to 200 days /played. That's a bit less than 2% of my entire life spent playing one game.
Given that I started during Burning Crusade which was released in 2007, that works out to approximately 14% of my time over the past 4 years spent playing one particular game. But...of those four years, I was only actually playing for two of them, because I stopped playing about halway through WotLK, started up again for Cata, then stopped after several months. So, during the ~two years I had active accounts, I was averaging about 6.5 hours a day. For two years. Which, oddly, now that I do the math is much less than I expected. I was guessing it would be closer to 10 hours a day. I certainly remember enough weeks of playing 12-14 hours a day.
In any case, 6.5 hours a day for two years...WoW probably wins on that account. However, looking over some other posts in the thread:
Civilization
Europa Universalis
Angband
Diablo
Hellmoo
Master of Orion
Morrowind
Dwarf Fortress
X-Com: UFO Defence.
Star Control 2
I've played all of these. Some of them I've played through multiple times. And some of them I've played multiple games in their series. WoW is definitely the singlemost game I've played, but I don't think I've played it more than every other game I've played. Between moria, angband, ToME, DBT, Cthangband, etc. it's possible I've spent more sheer hours playing even just roguelikes than WoW. I only spent two years playing WoW. I've been playing roguelikes for most of my life.
*shrug*
<-- is a gamer
I'd be curious to see a /played count for all my gaming hours of all games combined.
