You get gold by looting treasure, which will automatically be kept in a little inventory bank I've got for y'all. So, instead of weight or reality, number of items will depend on space in your bank. The limit is on weapons; you can only have up to three, and that's if you have three hands or have any form of holstering e.g. the bracket, an x-sword holder or a belt.
I'll edit this into the original rules, seeing how I failed to inform you.
Also, after this battle we'll have a more refined ruleset, meaning I can run a second battle to compare results of two teams, and then others are free to either use my rules or their own and run something similar.
