Valve’s latest experimental Steam feature is Play Next. It’s designed to recommend games for you to play from what you already own, based on what you’ve played before. It only recommends stuff you haven’t played, so if you’re one of those people that buys games and forgets about them it’s a pretty good reminder of what you’ve got waiting for you in your library.
My Play Next page reckons I should give Borderlands: The Pre-Sequel a go, because I’ve played loads of Borderlands 2 and Risk Of Rain 2. I didn’t even know I owned The Pre-Sequel so I suppose it’s done a pretty good job scouring my library to find that one.
