BT writes: We have covered a lot of XBLA gems over the course of our Xbox 360 25-in-25. Games like Braid and Limbo made Microsoft’s seventh generation home console the ultimate destination for indie games–especially puzzle platformers–for a number of years. Many of these titles eventually ended up on Steam and the PSN, but almost all of them started off as exclusives. A fair few of these projects flourished because of the direct support of Microsoft, whether through financial arrangements or just the availability of the XNA tool-set. The Misadventures of P.B. Winterbottom is a strange and wonderful exception.
