Carlos,
If it would be alright, I'd like to change my submission to Wildest
Kingdom Chess. I took some time today to re-create my preset, adding the
new porcupine graphics (Fergus, could you please upload those so I can
complete the preset?), updating the rules page to reflect the porcupine.
This game has been tested/played on several occasions on the site, just not
with an official preset. It might be too difficult for Fergus to program,
but I think my rules page makes everything really clear. Once the
porcupine pieces are uploaded, I'll post the preset. For now, you can
review the rules at wildestkingdomchess.webs.com. Thanks!
