Not really an injury, but this game is a serious workout.
I was on a long trip via greyhound and had like a 30 minute stop at one station. It was the middle of the night.. tons of shady people around.. but they had a small arcade section in between the station and the attached convenience store. There was an arcade game called Police 911.
It's a light gun game.. but this one also tracks the players posture... So to move behind cover, you physically crouch or move to the side. It was a really fun game. Spent like 20 minutes playing. Ran out of quarters so I go to sit and wait for my bus. Bus arrives and I found could barely stand upright because I was inadvertently doing tons of rapid squats whilst playing.
Also.. mgs torture mashing.
