Map-making, zombie-breaking, tank-driving, pony-trapping.
Etrian Odyssey (US Import)
Cartography is a profession woefully under-represented in videogames. We're used to having our in-game maps fully charted and available right from the start of a level (or, in the case of Zelda at least implausibly awaiting discovery in some remote treasure chest). As a result, few modern gamers will have experienced the antiquated and inimitable enjoyment that comes from painstakingly mapping a level, square by square on school maths paper.
Etrain Odyssey takes this ancient RPG hobbyist practice and boots it into the present by offering a turn-based first person perspective RPG on the top screen and a fully-featured mapping tool on the bottom.
