Ya, $80 BYOP is steep. Well, it actually could work out in your favor if you consider that it would be cheaper than playing the 26 hour Viper games there.
Viper game: $45 entry + $15 air = $60. Then add $65 per case of paint you are going to shoot.
This game is $80 air included so thats only $20 over what you are normally paying. Do you think you can save that extra $20 bucks in paint costs? Sure you can, barely if you just shoot one case but shoot 2 or 3 cases and you come out well ahead.
Still way too much for a game that no one knows what its gonna be like or what the turn out will be like. I wouldn't pay those prices for anything but a 26 hour Viper game or something comparable. Not a "big game".
