Couple of thoughts off the top of my head after playing it for the first time:
1. This was definitely not the game to show off the new high powered HD system. I am no tech head so maybe I am missing something but the visuals definitelty did not inspire awe.
2. The games are not what I was expecting at all. I was thinking Mario Party minigame easy but these games take skill and are much more complicated than that. I tried out Donkey Kong's Crash Course and Octopus Dance and loved them both. Making faces at the gamepad camera so my kids could see me on the submarine floating in the background of Octopus Dance had them cracking up.
3. What are the treasure for? Do they do anything or are they just collectables?
4. The coin drop game is kind of lame. Nothing more than a Plinko ripoff.
I was shocked when I saw that Gamespot gave this game an 8 but after spending some time with it I can see that it is much more than I thought it was going to be. Definitely shows you what the gamepad can do.
