Several Bond games have been released for different generations of consoles. While some games have had the same title of a Bond film, others have been completely separate entities. None have been released at the same as the movie though, which is atypical of movie game releases. Activision is going to change that with the upcoming Bond game Quantum of Solace.
When you take a look at the previous Bond games, you see a character that looks like Bond, but you really haven't seen Bond as you'd expect him. Previous games have had a generic-looking Bond, but Quantum of Solace features the likeness of Daniel Craig. This gives the game a greater connection to the current Bond films.
