Belatedly, I don't have a special interest in fixed-camera games, but I think we should talk more about technique and aesthetics in games. Nowadays it's all lumped under "3D" as if only GPU features mattered. Then "serious" developers wonder why games still aren't taken seriously as an art form. And actually they are, but... only those games whose creators treat them like art, and not glorified tech demos.
Of course, the big problem with fixed-camera games is that you still need a full 3D engine, with all the issues arising from that, including content creation. But then again even so-called pseudo-3D games with limited renderers that take shortcuts are much more 3D than technology snobs realize.
