I have the game now. Here are some impressions.
1. Story cut-sequences ARE entirely skippable. The IGN reviewer must have had a different version of the game. When you replay a level for a better score, you can replay from the beginning of the story sequence (where you can then press a button and skip it) or you can restart right at the start of the level itself. No wading through cumbersome dialogue all over again. Since I never died at the first boss, I can't say whether it forces you to start the entire world over again, as suggested by the reviews.
2. I haven't played the infamous 'on foot' maze levels yet but I assume they're about as fun as Sonic Adventure's Big the Cat levels (not very).
3. Music is fantastic.
4. Graphics are choppy, inconsistant, prone to tearing, and look like the Dreamcast. Because of my nostalgia for the DC, I don't mind this too much, but the price point should be closer to $29.99.
5. I used the classic controller and had no problems controlling NiGHTS. The game actually suggests that newer players use the classic controller and that they only move to the standard Wii controls later on when they've become more accustomed to the controls.
6. The "My Dream" garden is a strange green square filled with the various bad/good guys you collect while you're flying. The game suggests that joining these types of creatures will create an egg and hatch a new creature... however, I wasn't able to get this to work.
7. The game has a lot in common with the Sonic Adventure series, flaws and all. This is not so much of a problem for me as I enoyed those, but I recognize that they're far from perfect and don't appeal to everyone. I'm not surprised the game hasn't sold well.
8. I doubt we'll be seeing another NiGHTS game anytime soon.
