Favourite weapon has to be the explosive egg. Especially when computer players think there is an item inside the egg, so they throw it downwards and instead it explodes in their face.For conventional items, probably the beam sword. Home run bat is good, but takes a while to execute and doesn't "always" kill. And hammer is just... cheap
Although it's not on the list, i would say Super Mario RPG, that's one of the classic rpg console game i've ever played.For voting purposes, ff7 takes my vote.
