ATLUS has a 3DS eshop sell: I'm going to buy Devil Survivor Overclocked or SMTIV

[Super_Boom]

I preferred Overclocked to IV, both in story and characters, but they're both fun. Like Soriku said, Overclocked isn't a traditional tactical RPG, it's more like a standard RPG with a grid map and skills.

Though, if you only want a traditional RPG, then you'd probably prefer IV.
