which version should i buy?

Soul Silver. Much better than a giant chicken.

hmm what is the difference between them?

Just basically Pokemon you can catch from what I've seen.

heart gold ftw ho-oh has way better offensive stats, and with the ability of sacred fire you cut all enemies attack in half if you burn them, but it really don't matter what game you get cause you get ho-oh and lugia in both games.

stealth rock > ho-oh

Main difference in games as like said , you get different pokes in them

ha those same games i got too

Get Heart Gold since most people here have Silver from what I've seen. xD

what pokemon you cant get in SS/HG?
