I like the weapons in the Dark Cloud games. You can upgrade them exactly how you want, and invent new ones out of idea you get from taking photographs of the worlds around you.

Portal Gun and Gravity Gun. They just kinda pwn...shooting people with metal barrels lolz

Ivy's sword from Soul Calibur.

I'd choose a huge staff and for attack.. uhmm.. Firaga ^^

Any weapon that can pack a punch (which is usually a sword or blade) and any magic spell that keeps me from dying (heal, cure, restore,ect).
