end of the day though, Delta Force is a business and businesses are usually out to make money. To be honest, i used to think the same: ripoff, con artists etc. but when i look back now, after many years of playing, they are just another business out to provide a good time. yes, they are expensive but some businesses are, even outside of paintball.
For those who have played at a Delta Force (ive played at 5 seperate sites, still do), you can see that the money they make doesn't all go into their pockets. Their sites are well developed with many great game zones with many great buildings such as 2 tier forts, double decker buses, huts to even a Chinook helicopter. Maintaining such a site is no doubt expensive as well.
