I don't know, I didn't really find any of them to be unforgiving, per se (well, except for a handful of the races).  Most of them I found myself wondering at how I'd had trouble with them the first time around when I tried them again on my second go-through of the game.  My death count has gone from 315 to 155 to 50 across my fully completed play-throughs, and my current one's only got 4 deaths and 46 stars collected.  I think most of the "unforgiving stars" are just stars that you have an edge on if you know what's coming next.  Of course, that's true of most games.

I'm glad that you enjoy Super Mario Galaxy as it is one great game and I hope that you find many other great games (great for you that is) on the Wii so that its purchase is even more worthwhile.

As for Legend, shouldn't that be:

"The Wii on the other hand has no games that give me the urge to want to buy one... yet"

There is plenty of time for more games to come out and with the Wii's current success you can be sure that there will be plenty of 3rd party games that will come out for it too and it would be very surprising if no game interested you on it.

After all, with their poor 3rd party support both the N64 and GC had games like that so the odds are that the Wii will too.

I have 360 and Wii. Just started playing SMG today (Christmas present)
Only got 10 stars so far.
To be honest, it's an OK game. Maybe it'll get better.

I think I'll start playing Naruto on 360 (another Christmas present) and see if its any better

It will.. the first 40 stars are really blah and easy. After that it picks up.

 I'm a Wii owner who did not like SMG so yea.

no always knew galaxy would be danm fantastic, and it is =D (got it christmas)

hahaha @ soulless people and picking on Legend.
