Etrian Odyssey is really hard

[A Black Falcon]

Oldschool-style first-person dungeon crawling RPG from Atlus. You have to make the map on the lower screen as you go, while you play on the upper one. It feels very much like an '80s PC-style RPG, with console stylings like limited saving and anime-style artwork (and, as with most console RPGs, a less complex game system than most PC RPGs have)... quite good game. As I said though, it's also very difficult...
