That sounds pretty good, the concept sounds solid for people that play paintball on daily basis. Adding a game center is a bonus.
Make sure to add some out door paintball matches, not all just in doors. Even a level paintball match where you can only play it in the rain or out doors in general. Example; Downpour Call of Duty 4 Map.
Hosting tournaments for cash would lure people in a heart beat.
Laser tag, is that for younger kids?
Also think about the adults, for thoughs that aren’t into gaming or paintball, but without going crazy. Maybe a place for them to sit and watch the match looking down on the terrain. Just a thought.
We need gaming centers to be spread out in key areas, not just the typical areas that game tournaments are held these days in the US and around the world.
If I have anything else that hits me for an idea, I’ll post another. Good luck.
