All who know WiiWare, that Nintendo not does a great support to the function that allows players to download games online with Wii Points can be purchased with credit card or Wii Points Card.
Only games I bought off of WiiWare were Mega Man 9 and 10, but those were revivals of a series that's mostly available on the Virtual Console at the time of writing this.
Personally, it's a nice little extra for buying games, but none of them seem appealing to me, just like most game store wares out there. So I suppose that means it's doing good.
Make the games (Excluding MM9 and MM10, perhaps Pokemon Rumble too) appeal to one's attention span for more than an hour is my idea of an improvement.
My wii broke. It doesnt work. Cant play a single game and uselly freezes. HOWEVER. Wiiware is very reliable. If your wii can turn on, your wiiware game's work! I got the original paper mario, super mario bros. 2 and 1, the ORIGINAL legand of zelda, and mario golf....oh yeah, and punch out. Ill probley get Orcarina of time and majora's mask on wiiware if i get bored.
