Why not give real names as rewards for passing levels in a game?

For example, you might choose real names of people who have accomplished something great (e.g., wrote a free app that you like).

After passing a level in the game, the player would see the name of such a person.

I suspect many players will want to google the name to find out who this person is and what he/she accomplished.

Maybe the people mentioned in the game will want to check it out and mention it to their friends, thus making the game more popular?
