At this bar here in Ottawa we have an annual Battle at the Bar-ics (though it just got renamed to that), everyone just gets drunk off 3 dollar double shots and watches people play skate, it's a tournament in the exact same format as the berrics, its fucking cool as hell, there's a game every Wednesday.
However this year they added a twist and made it in teams of 3.
On the offense, you must switch your skater every trick, however on defense, you can pick who tries which tricks, however one can only go a max of two tricks in a row. It's pretty cool because it incorporates a whole other level of involvement, everyone's drunk and shit just cheering for a team of their homeboys, there's also more strategy involved.
if its not already being done at a bar in your city, I highly suggest you lobby for this shit!
