I bought a DS game called Etrian Odyssey II a couple weeks ago and am loving every pain the game inflicts on me (well, OK, my characters...).
For those who never heard of the game, it is an rpg, in the tradition of old school rpgs such as Bards Tale and Might and Magic. Therefore the graphics won't wow you but if you miss these types of old school, you should check this game out. The main draw to the game is that it is really for hardcore rpgers. It never holds your hand and will have no qualms about TPKing your party very early in the game (my party died on the tutorial...). Another big draw is the cartography program that you use to map out the dungeons (the bottom screen is used to map out a dungeon). It is up to you to map out the dungeons yourself.
Anyway, back on topic. I came across this music video of the game and made me laugh out loud.http://www.youtube.com/watch?v=WM5MMqNgUzM&feature=related
For those of you who are a glutton for punishment, you really should check this game out.
