Summary: As stated, this is the spiritual successor to the PC wizardry games. As far as I know, it is only available for PSP. The psn download is less expensive. There is no dialogue between individual characters. You are addressed as a group by some npc's.
Summary: If you liked the older Wizardy type games, then you will love this one. It can be tedious at times, and you will have party members perminatly die, so a lot of people consider this game harsh. But its a lot of fun, if you like harder games.
Summary: Class of heroes takes a step back from today's modern rpg's such as Final fantasy XII and does a good job of doing so. Instead of full 3-D and a real time battle system it goes back to the time of games such as wizardry, which is completely menu driven.
Summary: Good battle, class and fighting systems, so great core mechanics. As many of the more obscure japanese rpgs, a clunky and complicated interface will make sure to scare any casual players or gamers seeking a way into dungeon crawlers. For those, I suggest Etrian Odyssey on the DS.
