I can't say I'm a "paintball player" but I have gone paintballing about 20 times. I'm pretty much sick of it. The thing is we keep going to the same field and maybe that's why I get bored. Also the guns we rent are pretty crappy.
Aha, that's why you gotta buy yourself a gun. I have about $1500 worth of paintball gear, it changes the entire experience.
When you have your own gun and gear, the game becomes a whole lot better. I play with the pros and lemme tell you, it's one hell of a thrill, beats playing with a bunch of newbies who come and don't know what their doing.
Btw, what did you play? Woodsball? Speedball? Xball?
