Ok, i've seen this activity in some forums, so i decided to put it here, just to have some fun with the community <3
Let me explain:
The user number 1 post an image of one game... any game of any console... the only condition is that it must be difficult to guess.
The user number 2 and any other user must guess the game of the number 1 user's image... don't be affraid of post, this is only a game. Only 1 guessing per post, and only 1 post per user, at least until the subject 1 accept or deny all the game proposing of the users.
If user number 3 hit the correct answer, then him/her should post the next title that the users should guess. If user 4 guessed the game as well, then the first user that guessed it is the winner, no matter how many users guessed it too.
Recomendations: think about difficult-to-guess games (AKA no Mario, no Zelda, no Halo, etc.) and don't use Google images without modifying themselves, because the users could search the game via the image you posted. Also, upload the image to some image hosting (imageshack, tinypic, even Dropbox), that way the other people couldn't seek in the URL for the game's name.
So... that's it... sorry about my terrible english, i hope you understand all of the rules. If not, then ask :))
Here's the first game to guess!
