People can afford paintball.. Hell, When there was 'Walk-on' Nights in my local PB Field, All you saw was $800+ Guns.. I was the only one with a 'Shitty $400 Autococker'.
And let me tell you, I sat behind those bunkers, and just plucked people off. I could see the stream of paint coming towards me, and I just ducked back down..
Paintball is about a stand off, and Luck.
Airsoft is about realism, and Precision.
^^ At least, that's the way I look at it.
I got into airsoft because of the realism factor. Paintball can't come close for the realism.
