Kingdom Hearts - I'm talking about the series in general but if there was one game that sucked all my time it was KH2. @_@; But... I've got well over 100 hours each on all the games ('cept the first). I've played through KH1 twice, KH2 about 4 times (two of which were *compete* playthroughs), CoM about 5 times lmfao, Re:COM twice... and 358/2 has 110 hours on it. Some of those are translation hours though. XD;
Tales of the Abyss - I have well over 300 hours in this, I think, if you add up all my files. I played through on my own and then every subsequent playthrough was with a friend. Completion took forever but it was so, so satisfying. Tack on all the time I spent in the fandom and talking about it and you've got an innumerable amount of time.
The World Ends With You - I don't remember how many hours I have on this game but... I would definitely say the requirements for completion wasted a LOT of my time. XD; I poured hours into this game, some of it just mundane pin levelling. orz.
Pokemon - If the entire KH series counts (even if... most of it would count in its own respect lmao), then Pokemon counts. I've got at least 60 hours on each one of my games (probably even most of the spin-offs, too) so... just... gah, wow what a timesink. XD
Assassin's Creed - To get my complete file I had to play through this like 3 more times so one templar would appear. >8| Not as many hours spent as on other games but certainly plenty wasted lmfao.
