A post on Occasional Gamer, the XNA development blog of Elbert Perez, offers some sales data for Scribble Defense on Xbox LIVE and some accompanying thoughts from the creator of this offbeat tower defense game on what they represent. He reflects on the game's conversion rate from trial to full version, and the effort an indie title requires at marketing to get the word out. True to that, the page where he links to get the Xbox LIVE trial version also has a PC edition to sample or buy, which we were not aware of before now. Word is the PC edition requires XNA 3.1 Redistributable and .net 3.0, which are both conveniently included in the installer.
