I love a good dungeon crawler. They're perfect when you want to get away from silly RPG stories and focus on the fight. Wait -- you can never get away from the silly RPG stories. What am I saying?
In Class of Heroes for the PSP, you're a student in a school that specializes in teaching those that would crawl dungeons. You'll go on quests as assignments, making your way through dungeons in first-person RPG style, working toward that eventual goal of dungeon master. It sounds like you'll be working for awhile though, as this game is 80 hours long, packed with 75 maps, 500 character possibilities, and an alchemy system that sports over 400 recipes.
Atlus says that Class of Heroes says that this title drops in April 7th. Check out the official Web page to see more of this upcoming title, including the first of what looks to be many four-panel comic strips.
