NC: I downloaded the Nintendo 3DS eShop demo for Square Enix’s Heroes of Ruin a few weeks ago just to try it out. After downloading the demo, I was instantly sucked in! I mean, how can a demo keep you playing for so long? Well, Heroes of Ruin proved it was, in fact possible. I think this is the only demo where I have used up all the uses. This is a dungeon crawler game and there was a lot of hype for it. Is this an RPG worth your time?
