Their new website just launched today with quite a bit of information on the game. First off, it has been in development for two years and yes, it is influenced by TONS of stuff of which the most notable are Minecraft, Monster Hunter and in my personal opinion 3D Dot Game Heroes and ClaDun 2.
In this game it is pretty much like Minecraft in that the world is "infinite" or in realistic terms: Really fucking large. So you'll be an explorer/adventurer FOREVER. Like Adol the Red (20+ years and still no closure in Ys...). Combat has a Monster Hunter tinge to it. If you at least watched Monster Hunter in action, you'll see it. The rest... I'll let the website talk:

Overall, I think the game is very ambitious (a good or bad thing) but since the dude has been working on this for two years already, I think it is safe to say the dev couple are committed to the game (Say unlike Notch to Minecraft. He jumped once he had the chance). In its raw state right now, it looks repetitive but hat is fine. What "infinite" world game can't be like that?
Anyways, the game will be released for PC (with Mac and console some other time...). The structure will be like Minecraft. So alpha, beta and all that good stuff since those words don't mean jack anymore. Still, I'm looking forward to it, even if it is for the sheer novelty of it all (and if it crashes in a year or two after release).
