The capabilities of modern consoles are constantly expanding but "laser tag scorekeeper" is one we never expected. Ubisoft just announced Battle Tag
for this year, a game-- err ... application that keeps track of a laser tag game you play with included blasters and hit-detecting vests. Near as we can tell, it's a real laser tag game, but your expensive game console (platforms are unannounced) keeps score for you.
: Gone but not forgotten.
