4. The Rock
The fact 2K put The Rock on the cover of the very first WWE 2K game, it tells you all you need to know about his importance. His image sells products, and his inclusion in 2K16 will be the same story. People the world over, many with no knowledge in pro wrestling, will buy simply because they know The Rock. He's that Hulk Hogan level of performer, a wrestler who transcended wrestling and became part of the global pop culture fabric. As the most famous pro wrestler in the world, many gamers who buy 2K16 will go directly to Rocky. It is a bit like FIFA and Ronaldo, Rock and Ronaldo aren't necessarily the cover stars, but they're what all gamers look towards when playing.
