We sometimes run funky casual tournaments in between standard format tournaments, and these are the rules we're going to use for a mini-tournament in a couple of days. The idea is that you build your ships from the chassis up, with lots of unusual customization options for the fun of it. It's possible there are some totally broken combos in here, but I'm going to have all the players take a look over it to try to catch the biggest breaks, and I'll issue a corrected version of the rules if necessary.

EDIT: The rules PDF has been updated. Posts 1-18 in this thread were discussing the original (quite flawed) rules.
