Bought three of the WiiWare launch games:
LostWinds: Haven't played it a lot so far, but the wind mechanic is really interesting. It's really fun manipulating the different things in the environment, and Toku (main character) at the same time. If you were thinking of buying a WiiWare game, you should definitely consider this.
Pop: ADDICTING. The gameplay is so simple, yet has a lot of depth for what it is, which makes it addicting. I've spent a lot of time on this one so far, improving my high score for the most part.
V.I.P. Casino: Blackjack: I have no clue why I bought this. Definitely
not worth 700 Wii points. I mean, its fine for what it is supposed to do, and that is simulate Blackjack, but thats it. It's that simple. Nothing more, nothing less. Should have been priced 300 points imo.
Also it is becoming painfully apparent that I need more storage on my Wii. Down to about 200 blocks I think. A external hard drive NEEDS to be released now that WiiWare is out.
