No. Petitions never do anything on games. The amount of code writing and rewriting it would take to incorporate all of those items would be phenominal. They won't bring any of the items to Gaia unless they had already planned to bring it in here.
Actually, the staff here answer petitions all the time! 3nodding Not to mention, Gaia isn't a game; it's a forum site. c:
As for this particular petition, there may be some issues with legality. But they really do look at the petitions/suggestions.
XD Finally someone realized this after oh what 9 years? XD biggrin I love you! From what I seen though I think that since Gonline took down their site I think Gaia has the RIGHT to take their items.
