Can't name a single one but it depends where I find myself. Soccer when there is a nice green ground with  a post and many players.Cricket when its not too much hot with a good bouncing  pitch.Table tennis when there are few  people having a  good wrist swings.Chess when there is a tricky suspicious smart  opponent.Swimming when the pool is near.Carremboard when you are left alone with the kids of your relatives.Tekken and Call of Duty in Xbox when you're just lazy and still want to play something.
