Erm, the game sold cubes, so there must be a demand for it even among the non-RPG-starved crowd...
From what I've read so far the game is pretty good even compared to other RPGs, especially since it has a combat system that's actually fun (Oy! Rarity!). I hope it doesn't turn out like Harvest Moon which I eagerly anticipated just to play it 2 hours and shelve it. I'm not sure how valid my oppinions on the game will be to others, I never played any traditional RPG more modern than Skies (there were a few MMORPGs and unconventional RPGs, though).
