WCS is a cracking pin, great flow, awesome sound and callouts and a good ruleset. Soccer is clearly not a huge theme in the US, and neither is it in Australia, but that doesn't bother me, it's just damn fun, and thats what pinball is all about. I have no doubt, that if WCS, JM and TS had better themes they'd be considered 'A' titles. There is a reason Bowen Kerins has owned WCS for such a long time. What it's worth though the market will determine I suppose.
Good luck selling... or not
