They say that all good things must come to an end but Microsoft is making sure it won't end on a sad note. Xbox One's Backward Compatibility program surprised the industry for pulling off something some thought would be both technically infeasible and also a bad business move. Over that time, the program has added more than 600 titles from the original Xbox, a.k.a. the Xbox Classic, and the Xbox 360, becoming available to all generations of Xbox One consoles. Sadly, that library will no longer grow after this week but Microsoft promises not to worry because it'll be back soon.
