Ghost Recon: Advanced Warfighter - Xbox 360 - 10 hours

I noticed this list has not been updated in a long while, is this list now dead?

No one has been voting games. I was last before you and it's been over a month.

Pokemon Black/White - 26 hours. This is how long it took me to beat all 8 gym leaders, the Elite 4, and the boss of the game. This does not include catching rare pokemon in the post game.

Valkyria Chronicles - 25 hours. How did you take 33 hours? There are only 19 chapters in the game, most of which are an hour long.

Lost Odyssey -100% Completion - 62 Hours, including DLC However I missed 1 treasure chest somewhere, I spent a good 5 hours backtracking looking for it with a guide with no luck. 1 damn tresure chest prevents me from completing the game!

Lost Planet - 100% Completion - 125 hours

Does anybody know how long does it take to complete Castlevania Lord of shadows?

Freespace: 16 hours - First time playing, completed the campaign.

Freespace: Silent Threat: 5 hours - First time playing, completed the campaign.

Freespace 2: 16 hours -First time playing, completed the campaign.

It took me around 13 hours.

Finally completed the game. It took me 36 hours to beat the entire game, post game, and every trainer in the game. I didn't collect all the native pokemon to the game, but I have most of them. I don't think it's fair to count completing the pokedex as completing the entire game because you need to trade with other games to complete the pokedex, and I'm not even sure if you can transfer over all the first gen pokemon over.

Ninja Blade - 8 hours

Red Faction: Armageddon - 7 hours

Battlefield 3 - Around 6 hour 30 mins on normal.

I swear I heard of someone beating Final Fantasy XII in around 24 hours, including Yiazmat.

EDIT - Seems he just went and beat Yiazmat within the start of the game in 24 gameplay hours, which is no easy feat since you need to do a bunch of things before you're able to fight it. I'm sure it's entirely possible to do a speedrun of just the main game of FFXII in 20ish hours or under.

Starcraft II takes about 12 hours on Normal (including retries, cutscenes, dialogue etc) for the first time. I can speedrun it in WAY less on Brutal. I think someone did it in 3 hours. If I can find a link, I'll share.

Also, Demon's Souls was speedrun in 54 minutes and 54 seconds, which is insane. Personally speaking I can do it in about 6.
