Additional thought:

The metroid prime: first hunt demo is really a split decision I've found.

A lot of people count it as part of their collection, I personally dont but it really depends on who you ask.

If metroid prime: first hunt were a tech demo or something that had the gameplay it currently has i'd probably be inclined to include it in the list but since in 2006 we will be seeing a more complete version of the game its hard for me to list it as part of the release list.

I think when the full game comes out it would be kinda confusing to some people to list the collection as

"metroid prime: first hunt"

"Metroid prime hunters"

People that didnt give the DS any attention in the early days would think it was a metroid zero mission type deal and think they are two different games entirely. thats why ive found it easier just to label it as a demo even though as far as demos come it has a lot of depth to it compared to other demos.
