You missed the point. NPPL works because it's the players who ultimately pay the bills through entry fees and buying stuff from the vendors who pay vendor fees. Since there are enough paintball "players' looking to party for the weekend, that's ok.
NXL is going for something different - they want to entertain an AUDIENCE. The audience doesn't care about the kind of entertainment NPPL provides, because they're not there, they're at home in their living room, and they're assuming they're watching a sport. If you put it on TV and your reffing is horrible and the format is boring, it's not going to last.
THAT is the difference. NPPL may be better at entertaining paintball players looking to party for a weekend, but NXL kills them in being a sport. While NPPL may get the short-term glory, if they don't change, it'll be the NXL that has the long term future, because the REAL money comes from a wide audience and out-of-industry sponsorship.
500,000 TV viewers once a week is worth much, much more than 1,500 players five times a year.
i'm not saying one is right and one is wrong, but it's silly to think that the NPPL way is the only way. Some people would rather have carpet on a parking lot next to a stadium, and some people would rather have plush grass in BFE Pennsylvania. Just because you happen to be a carpet fan doesn't mean there are not enough grass people for PSP to be successful.
