Herro there pyromaniac. I am Isaac55, and I like soy sauce.
I'd say beating hard mode in Radiant Dawn is quite an accomplishment, since Battle Saves are completely removed, unlike in Shadow Dragon. Still, you may want to try shadow dragons H5 (merciless) mode, as it can be quite challenging, at least at the beginning. I find it to be more difficult than RD hard mode, but more convenient since there are limited battle saves.
