Gaming and celebrity involvement has gone through a weird trajectory - mostly lining up with how mainstream games themselves started to be across the late 2000s.
From David Bowie in Omikron: the Nomad Soul to Rockstar using GTA 3’s revenue to put EVERYONE in Vice City and San Andreas, today chances are if a celebrity is in a game, they’re a fundamental part of the marketing campaign.
Go back through gaming history though and there are some insane crossovers of random contract work, touching tributes or people who would go on to *become* insanely famous later down the line.
10. Conan O' Brien & Andy Richter - Halo 4
Quite a lot of fans hopped off the Halo train when they realised Bungie weren't driving it any more, and although 343 Industries make for amicable hosts, there can be something initially off-putting about a new team taking over a franchise you've grown to love over the years.
They managed to totally nail it though, and as we're seeing with both them and Sledgehammer Games' overtaking on the development of Call of Duty: Advanced Warfare, sometimes letting a team of people who were previously fans of something get full creative control can be a truly awesome thing.
Halo 4 is just as packed with details as the previous trilogy, and here although their lines are a bit flat on delivery, you can see tucked away in the corner of one of the hangar areas is a hidden conversation between the Clueless Gamer himself and Mr. Richter.
