The Nintendo DS was three years away. The iPhone was six years away (yes, Nintendo did it first and people often don't remember that).

My recollection of following the absolutely ridiculous hype cycle is that they were talking about the mouse being your hand inside the game and pretty much nothing else, but it was remarkable prescient in terms of how that would work without the mouse on the way.

I don’t think so. Touchscreens were not at all common in 2001.

There was an expensive glove accessory it had comparability with, the "P5 Glove" I remember it being called. (WHY do I remember this?)

I imagine that would have been super neat or crazy frustrating to use haha.
