Would a huge injection of cash suddely make people want to play? Can't see how, people are drifting into (and out of) paintball all the time, and there is no massive cash floating round (well, there is, obviously, but not from sports status or government or etc).
Say for example "The Cook$ Centre for Paintballing Excellence and Tepanyaki Grill" opened, due to the general apathy of ballers, I'd only get visitors from the surrounding locale. If I opened it in my back garden in Wrexham, they'd still go to the NQuarter if it were closer.
But would it make new players want to start? if there is a paintballing practise centre opening? No, they'd still go and play rec-ball once or twice a lifetime with their mates, and then only if it were cheap. Cash injections/advertising/corporate logos would only make a difference if prices came down, which they won't.
