Nuzlocke skipped tonight due to tiredness. Long day.
I'm not playing them at present, but Dragon Warrior Monsters and DWM: Cobi's Jouney are both very good games. At least, I remember them as excellent from my younger days. And DOOO NOOOT forget Dragon Warrior III and Dragon Warrior I&II if you're looking for good RPGs from the olden days. I also recommend "Final Fantasy Adventure", better known as Sword of Mana, and the "Final Fantasy Legend" (SaGa) series.
And Crystalis. Mustn't forget Crystalis. And if you want a unique RPG, try out Magi-NatioN, which I HIGHLY recommend.
...Uh, kind of going senile here. Any other GBC-era games I should be recommending here?
(Note: I'm ONLY doing ones I already had. I likewise advise sticking only to games you once owned - yeah, makes no difference in legal-status, but it's... the principle of the thing. If you never had the chance to pick 'rm up, though... *shrug* At least they're getting exposure? :\ )
