Basil, I still don't see how they target different users other than in marketing and HW features. The games cater to largely the same audience. Escape Plan is a dark game, I agree, but it isn't complex, that it isn't. As such, Any puzzle game is as complex as it. So artistic design I'll agree it caters to the older, but not complexity really. Only thing I see is that users need to think as to how to use their environment to progress, but that's not unheard of. Soundshapes is probably as complex as VVVVV, which is on the e-shop, and the e-shop has pushmo also, a Nintendo exclusive. There are alot of complex puzzlers on top of that like Crush 3D, so once again it's not fact what you're saying.
