i really like the final fantasys some better then the others buy still hardly any can compare to final fantasy
Ragnarok Online. MMORPG currently in beta.
in my mind, the greatest rpg of all time is phantasy star II for the sega genesis. it's kinda old-school, but the story line and maps really bring back some fond memories.
Ooh I forgot. My favorite single player RPG was Dungeon Siege. It probably doens't cost too much and is extremely fun.
