Earlier, we told you that Amazon had begun selling Xbox Live Arcade titles through their website. Continuing its march for digital purchase domination, the online retailing giant has begun offering WiiWare games, with World of Goo being the first out of the gate. The game is being offered at full price, which does not really make sense as the whole draw of the XBLA offer was the discount. If Amazon is reading this, drop the price a bit and gamers will come, we promise.
