Played about 11 hours of Recettear: An Item Shop's Tale. It's pretty fun. Some parts of the game (the multiple possible adventurers, the fusion system) seem like they can't really be used the first time through–you're on a fairly tight schedule, so there's not too much time for experimentation.
It does have a nice way of dealing with a game over: you restart the game with all your levels and current inventory intact, which makes it much easier to meet the requirements the next time though–possibly too easy, though. I'll probably follow up on this when I've completed the game.
