I'm surprised you guys don't like Ski as I have the opposite opinion! I couldn't stand Twister race and thought Ski was miles better. I could just be biased towards Jimmy T. though.
I've got to the bowling stage and love it so far. The mini-games are very hit and miss, and it's certainly not a patch on the Wii game (but I hold that as the best in the series by far), but it's still very enjoyable. So much character, and the chicken eggs keep me wanting to come back for more.
Stand out games so far - 18 Volt! It was a right task getting a score of 40 but I managed it. 9 Volt is also pretty awesome but I enjoy the other mode more because of the pure WarioWare aspect. I was also very surprised by Ashley's stage, it looked so dull but is actually pretty awesome.
Stand out has to be the pirate game though. Oh my GOD. That game is so good, I wish they'd make an entire eShop title of it. Can't get enough, and the dancing at the end is just hilarious.
The taxi game is also worthy of a mention, very engaging and surprisingly hard (or maybe I'm just shit at multi-tasking).
So far, I'm impressed. I know its been getting bad reviews, but that's what I expected. I think Wario games have always been quite misunderstood. Also, the whole chicken thing seemed exciting at first but I'm getting far too many 'hints' and character profiles. I do LOVE the phone-calls though. Truly hilarious and take me right back to the days of WarioWare on GameCube when it seemed as though pretty much anything goes.
I am surprised by the lack of multi-player options though.. heck, that's the main reason I got it :p That said, the picture drawing game is amazing. Me and f00had had an awesome time on that - I can't wait to try it 5 player!
