I like RPG's, but I often find the progression is too slow sometimes, although one that did impress me for what it was a year or two ago, was mystic heroes. I normally play champions of norrath type thing, and now oblivion on ps3, but mystic heroes for ps2 was damn fun if I do say so, boss fight were interesting and impressive, general gameplay was fast paced and fun, and gave you enough level up-ing stuff to keep you involved all the time.
