Name three things that all games, no matter where they are located, have in common.

One you have to use your body or limbs, all use physical activities, and most use your brain may not be a lot of brain usage or just a little 
                                                Have a wonderful day :)

1.) Strategy. All games have a strategy in one form or another even if it has to do with standing in your seat and shouting to the next person when it's your turn - as silly as it may sound.
2.) Physical. You're playing the game no matter what even if you're just moving your lips which goes to the physical side of things.
3.) Age groups. Each game has a designated age group. I'm sure anyone can play them, of course, BUT tag wouldn't appeal to a two month old.
I hope all is well, and you pass! good luck, rockstar! (:
