Megadan, you're right with Amazing Mirror, I'll give you that, but I can't stand Canvas Curse for some reason. Just didn't feel like a proper Kirby game. Don't get me wrong, I love Kirby - especially Nightmare in Dreamland - and am eagerly awaiting the GameCube version (even if it comes to the Wii instead).
But Starfy is a VERY strong series that could appeal to the Western market. It has all the aspects of a game that could have great success here and it's a shame it's been overlooked so far. It's not like the games haven't done well in Japan, either. The current DS version has only been out a few weeks and is up to a healthy ~139,250 units and the GBA games did FAR better than that.
As for Mario, Hazuki, it's the classic game with new stuff. It can't be overly criticised for feeling a little old at times. It's exactly what fans have been clamouring for all these years. Will be interesting to see your take on the UK version...
