The official ID@Xbox Twitter page has confirmed that September 29 will be the final day to purchase games from Xbox Live Indie Games on Xbox 360, so you'd best be quick if you've been meaning to get round to it, as there's not long left to do so.
This isn't a shock, though, as Microsoft told indie developers two years ago that the program would be shut down, and if you're worried about the games you already own, don't be, as you can still re-download games you own and play the ones you have, but again, you should do this sooner rather than later.
The shift of emphasis is now on indie games on the Xbox One, then, but did you have a particular favourite on Xbox 360?
