it really depends on the game. a game like Zelda, I try to finish it, after that do unlockables then I get bored. usually I restart a game a few years later. a game like Mario Party or any other party game.... a few days.

Depending the game, played once final fantasy 7 for 8 hours straight and beat i like 20 times.

In WoW, my main, UD Rogue Zenfoldor Sargeras, had 148 days played, real time. My total characters played time was just over 200 days, 2 level 70's and a ton of alts. Account still active, haven't logged in, in 6 months, still frequent guild forums. Seriouscat.net.

So, just over 200 days of real time is the longest it's ever taken me to get bored.

The quickest I've ever gotten bored is 5 minutes. The game, God of Puzzle 2.

Names have been changed to protect the innocent.

As soon as I finish the game for first time I stop playing it...unless that game has some replayability value (for example New Game +).

Depends what games it is. if its a wrestling game then i can play it for hours on end, when i was a kid i played WCW mayhem almost everyday for a couple of hors without fail for well over a year
