Absolutely nothing is wrong with playing video games.
Its all based on what type of emotions you obtain from playing certain games. I personally have encountered first person online multi-player shooters to increase my heart rate because when i get really into them and am winning, it gets me excited which increases my heart rate, and when i get angry with the game, that also gets my heart rate going.
Any video game which is based on thrill and excitement tends to increase your heart rate as a side effect of the adrenaline induced to enhance perception and reflex.
It really does depend on what game one plays.
