Reviews for Monster Tale" (yes, that's a DS game, not 3DS) are coming in, and all the ones I've seen so far are positive.
You might remember hearing it described as pokemon-meets-metroid (raising your own monster to do platform exploration with varied skills). You might also remember it as the game that fought hard to have a young, non-sexed-up female protagonist.
I'm a little oversubscribed at the moment, but it is on my list of things to pick up at some point. (And considering that the 3DS is region protected scum of evil and I can't buy one, my DS wishlist will doubtless get picked up over time.)
