I've played at Paintball Games of Lubbock, which honestly isn't bad, but it comes nowhere near the service, variety of fields, or quality of feilds that Challenge Park has.
Review:
I just recently got into paintball and am already addicted. The people at Challenge Park helped me immensly when my marker was messing up. The fields there are awesome and really add to the overall experience. I will continue to play out there until the game of paintball grows boring, which it never will.
