stika: Chess and battleship? You're a military commander
Pac-man? You're eating ghosts
Arkanoid? You mean the game in which you pilot a ship and fight aliens?
Pong and Tetris are exceptions, so I'll give you those two
JMich: In Pac-Man you are not eating ghosts, the ghosts chase you. You are allowed to reverse the roles for a small amount of time under very specific conditions. So in essence, you are running away from something you can't fight. Power Fantasy, right.
Arkanoid is the early Breakout, where you control a paddle and break bricks with a ball. No aliens (except the final stage, 32 if I recall correctly).
Pong was one of the earliest videogames, thus the "all videogames were created as such" is already debunked.
Chess and Battleship are the video adaptations of the board games, so I'll give you those two as "Power Fantasy" games, or training tools, depending on how you want to see them.
Alan Turing and colleague D. G. Champernowne wrote a chess playing algorithm. At the time, there was not a computer powerful enough to run the algorithm. The algorithm was tested two times by human versus algorithm matches. The algorithm won once and lost once.
