The weekly sales on PSN and XBLA are amongst the highlights of my gaming week. What will appear this time; a selection of co-op friendly titles for next to nothing, or some overpriced DLC reduced to slightly less overpriced? Admittedly some of the weekly sales are less emphatic than others, but do you know what is a bargain? A game that is permanently reduced. This has just happened to Insanely Twisted Shadow Planet, now yours for 800 Microsoft Points, or as I like to call it - the price that all download games should be in the first place.
