Issue 13 of the free PlayStation 3 magazine, P3Zine, includes all the usual previews and reviews, but also has an editorial on how PSN is starting to show a different and more exciting trend to XBLA. Looking at the lists of the top 10 titles on both platforms, they comment "You could argue that it merely shows that Xbox Live Arcade appeals to a different audience to PSN, but that’s missing the point. Sony’s list is the one which will make heartening reading to small independent developers, proving that even those ideas that might seem relatively niche can have huge success at the right price. Seeing the superb Flow in pole position is particularly satisfying..." and go on to argue how Sony has managed to make a better platform for downloadable, casual games.
