(2013)

The “game” is nothing more than a high tech scam.

Steve Battier (Rutger Hauer) wins the game, and offers to pay hundreds of millions to Mr. Chan to keep his consciousness in the body of his young avatar. Mr. Chan (Chris Tashima) agrees, though notes Battier may not have long, even in the youthful body.

As Battier leaves, we see that he is still in his old body, but perceives himself to be young. The game apparently just alters the visual perception of the victor to believe they have won a youthful lease on life, but have actually gotten nothing in return, other than being conned out of millions.
