Wow that's cool.
What would make it better, if it was a shooter, they actually gave you laser-tag guns, and they had holographic technology to make Aliens you have to fight. Then you could fight them cooperatively with your buddies and that would pwn.
Especially if they "dropped" one on you while you are in the vents, LOL.
OMG best idea ever - Counterstrike IRL (as a game like that). Re-make maps like De_Dust, De_Dust2, and Office IRL and give the players costumes like the CT's and T's. That would make the Cyberathelete Leagues look stupid, and then it could really progress to being a sport, muahahha. Not sure what they would do for knifing people, but you'd probably have a dull plastic knife that all you have to do it hit them with it
Okay actually that isn't much different than paintball/laser-tag, but still would rock if they had counterstrike maps..
Okay, NOW I have the greatest idea of the day... Paintball in STORMTROOPER armor! Yeah!
