Etrian Odyssey is an old school RPG grindfest that's always been on Nintendo's portable consoles, and Etrian Odyssey IV is set to launch on 3DS in February. Atlus has been releasing trailers that focus on the different character classes, and this time around it's all about the Fortress, the series' version of a tank.
The 3DS could definitely use more hardcore RPGs, so we're looking forward to this one.
