...and yeah, motion sickness sets in.

You use the Wiimote to move your view, so it turns around very sluggishly.

Had 5 minutes of embarassingly muddy and choppy intro. Compared to GC Prince of Persia cut scenes, it was simply shameful.

On the radar, the blue "objective" dot indicated I needed to do something with some computers, but my nausea was progressing faster than my understanding.

It was enough to make me say, "well glad that was a rental." Should I press on? Will I get used to the camera and controls? Anyone else played this yet?

Keep playing...it might get better.

I figure Metroid Prime 3 is gonna be the first great FPS we get.

I've heard nothing but bad things, so I can't really help you out much.

Your experience sounds pretty much on level. :speechles
