Xbox had a really good showing on Sunday, its showcase at the tail end of a Summer Game Fest period that has at times felt rather glib managing to make people feel happy about video games again – at least for a little bit. It was full of the kind of quirky and interesting-looking games that in years past would have been reserved for PlayStation’s E3 showcase, with only a smattering of what you might call Big games with a capital B. That was until the end.
