Ideas

"(corry for my english)"
I suggest that you get this idea through a spelling checker if you've some time to do that. (Just a tip to make it easier to read; I'm not trying to offend you)

But I'm not sure if I understand your idea...
What do you mean with "from pc but the it must be played at real word"?
People need to take their computer to a certain location and play their game over there?

The game will be have two phase. The first is the mission and information for this from pc. The player must take a mission and collect information from pc (for example the mission is to meet the Bill Gates and take an autograph from him). The mission will be prepared from other users. After that the player must be collect information how can do the mission. The second phase is to arrange a trip to do it. If the mission is successful the player is winner of this game.
At the end all the winners of a time periot will take one mission and the player that do it will be the one winner.

I'm quite sure we've had games like that on the Internet in the Netherlands, especially for students (like a treasure hunt with clues in the real world).
Whether or not succesfull depends completely on the game and the money you can earn with it.

I think instead of doning online-offline games, just develop offline ones.
