Never mind the technology. The main difference between Microsoft Xbox360 and the PS3 is nothing to do with technology. It is all down to girls' knickers.
Obsessive hacks at kotaku.com did a side-by-side comparison of two versions of Soul Breed which is an RPG game that hit the PS3 last autumn which has now appeared on the Xbox 360.
The monster-killing and baby-making RPG requires punters to capture the hearts of game heroines to 'create' a successor. When you manage this there is a movie which we guess implies that there's some adult action going on... and then the new successor is then revealed.
Kotaku notes that the difference between the two versions comes down to knickers. For some reason the love interest in the Xbox360 version has a pair of slightly more sensible white silky pants, while the PS3 has something black and red which actually shows less in the buttock department.
Some people on the Japanese bulletin boards think this is something that needs in-depth discussion. We just wonder what the developers were thinking that day when they decided to swap knickers.
Developer One: "Shall we add improvements to the game, perhaps more weapons, motion sensor game play, make it more interesting?" Developer two: "Nah let's just change her pants so they reveal more." Developer One: "Yeah OK... lets make them white and silky…"
And thus humanity evolved.
