Now I have my PC sort of working (if not entirely stable) I'm rolling up my sleeves and tackling the backlog. First up: The Talos Principle. I loved the first few hours. It's all very Portal but with pleasingly pulpy sci-fi overtones. Already encountered a puzzle that melted my brain for a good half hour.
Also ARMA III is down to a tenner so I might pick up and try the Battle Royale mod my mates have been evangelising about for the past couple of months. "I spent all last night hiding in a bush! Then I died!" Can't wait.
