I watched that 20+ video of the game. Wow, you know this is exactly what I wanted to see.
I've seen a lot of the ingame graphics and it's clear that this game engine is almost Wii-like and for a console that's capable of high-quality HD gaming, the visuals are indeed a bit dissapointing.
But I like this, because it indeed looks like a real video game on something that's meant to be a family-centered venture.
I see adventure games being played in this manner. Though from the footage, I couldn't tell how much stuff was actually gameplay or just scripted events. There's a lot of both there.
