I played on a team long long ago, before "semi-automatic paint guns" came out (~1986-90)
Was a totally different game back then IMHO... when you could only hold 10 or 20 shots in the gun before you had to stop and reload. When "100 round hoppers" came out it was like "WOW... just think... you could just lay down huge swaths of paint, and you wouldn't have to be that accurate with any one given shot".
For me, that killed the fun of it... I started to see guys come out to play who just threw gobs and gobs of cash at buying more paint pellets, and it ended up becoming a game of "who could pull the trigger faster and pour more cash into their hopper" than anything else. I quit playing shortly after that; the fun was gone for me.
