Oh yeah! There are all kinds of cool games you could play with AR.

My old school used to get really into “assassin”. Some organizer would divide everyone into a big circle but everyone was only told their connection in one direction (ie everyone knew their target but nobody knew who was targeting them. This was in NYC. Kids would pull out Rayline Tracer Guns in the subway and pop each other. AR would be a much better way to do that.

Games like Pokemon Go would be much cooler with AR.
