Local entrepreneur Henk Rogers has been named chief executive officer of Avatar Reality, a Honolulu-based game studio he co-founded in 2006.

Rogers replaces Jim Sink, who left the company in January when it was restructured to focus on the development of applications for the iPhone operating system, an Avatar spokesman said.

Avatar Reality is the creator of the Blue Mars 3D platform that allows players to create social virtual worlds.

“I believe that the full potential of the Blue Mars platform and technology has yet to be realized,” Rogers said in a news release. “With this I am excited about the innovation to come and am fully committed to the sucess of the company and Blue Mars.”

Rogers is best known for introducing Tetris to the world market. He also is CEO of Blue Planet Software, the sole agent for the Tetris brand.
