Wii Ware is somewhere where devs can expirement without publishers having their own little say. Toki Tori is the best game on their i've played imo but that was a full game thats been rehashed for Wii Ware.
So many bold ideas so early into Wi iWares life - I think it's gonna set a few trends and help devs work out how to tap into the Wiis market with decent titles a little better.
MontanaHatchet - dont just look into Toki Tori, get it. It's the best £7.00 or so i've ever spent on a game, if you like Z&W style puzzle games you'll just love it.
