Add feature: game length?

In light of all the Mass Effect 2 hype I expect coming out of E3 in the next few days, I thought I might replay the first Mass Effect. However, I still have Chronicles of Riddick sitting on my shelf, and in trying to decide which to play first, I wanted to know how long a play-through of each would be. I know that generally Mass Effect is probably a much longer commitment than Riddick, but since I deleted my Mass Effect save and I've never played Riddick, I don't know by how much they differ.

I think this is far too subjective of a thing for the wiki...what takes one person 40 hours may take another person 10. Then you have difficulties, collectibles, side missions...

Hmm... maybe a good idea.  Or at least someone could put it somewhere in the description.

I try to incorporate play time into my reviews.

well let's put i to the test, how long did it take you to beat fallout 3? (just the main quests and maybe some side quests)?

26h 29min

This sounds to me like something that might have a place with a sentence or two in the description, but not Feature.

The time it takes to beat a game is debatable.

Was thinking about this earlier today and could not figure out a very good way to create such a system. Aside from games being implemented with some kind of feature which records people's actual gameplay time, I did not come up with a sensible solution. The reasonable thing to do, in my opinion, is to just be as descriptive (albeit brief) as you can about the contents of the game, such as the amount of levels, level sizes, unlockables, side-missions, stuff which will shorten or extend your experience with a game.
 
As some have already said, length is almost always subjective - there aren't many people who complete the same parts of the same games in the very same time frame. Just can't work that way. Interesting post, though.

• People actually used it - prolly the hardest to judge
• It was restricted to singleplayer

A "time spend playing the game" for user reviews would work though.
