Check out this game that's coming out on Steam on Sept 10th:
Recettear: An Item Shop's Tale
You play a girl who's forced to run an Item Shop for adventurers due to your dad skipping out on a loan. You also get to dungeon crawl with different characters. The demo is fun and it's so different, I'm looking forward to picking it up.

These two guys on the Something Awful forums wanted to get into the game industry doing localization of japanese games, so they contacted the makers of Recettear (sounds like Racket-Tear) and licensed the game to do the localization and publishing of it here in the states. It's an interesting story, and these dudes were able to get Steam and a couple of other online places to put it out, so this should be pretty successful for them.
