That's a nice price geared for parents that want a babysitter for 2 hours.
You'll see how far 450 paintballs last.... (approx 2 games for noobs) not far at all. When indoors. It's a gimmick.
I used to play tournament paintball, and my team would go through approximately 20-25 cases of paint. 20x 2000 paintballs... and that would be for approx 2 full games lasting a morning and afternoon session.
When practicing I go through 1.5-2 cases.
In woodsball you'll probably go through a 1 case, which will last you a whole day if you aren't shooting too much. Less if you don't want to shoot at all.
