Zexx, Would this be indoor or outdoor?
If it was indoor: In my opinion I would like to see a little town made of things like plywood with a good amount of buildings. So you can have a CQB, Capture the flag, and other types of small space games.
If it was outdoor: My opinion would be a nice large field, with little towns made into it. Now, with the outdoor. You could probably do a Capture the flag games and just fun death matches.
I don't know what kind of environment you need for laser tag, does light effect that lasers in anyway?
These are all my opinions thought, I'm not business adviser or anything.
