Dale North and I both had a grand old time with beat-'em-up Code of Princess at launch, and now you can too, at the reduced price of $29.99 on the 3DS eShop. Keep in mind that the online community is basically non-existent though, so you'll have to mostly play by yourself, or with friends.
Say what you will about digital games, but if price drops and sales like this were more commonplace on Nintendo platforms, they'd be a lot more competitive than they are now. As a collector, I love physical boxes, but at the same time, who can say no to a 95% off Steam sale?
