How are the first two games? The first one is pretty easy to find cheap around here.
Well if you can put up with shoddy Dynasty Warrior's gameplay and are one of those people all about the "experience" then maybe you'll like them
1 is a pretty poor game gameplay wise, but it it makes up for it with how different and strange it is. Even the music is really out there. The story and characters while not terribly fantastic are so strange and unlike most games that they are enthralling. The story may not actually be good, but you may be entertained by just where it decides to go and how dark and twisted it is.
2 is a better game, but more normal really. Typical jrpg plot and characters, but the actual better gameplay is at least acceptable. Still it seems like it was a lower budget production. It still has some dark stuff and even a few touching moments, but its nowhere near as interesting as the first game.
