Forza Horizon 2 - Nissan GTR
The game did on a couple of occasions freeze the 360 console whilst loading up the menu or rewarding me with credits. Thankfully it did not lose any progress or corrupt my game save.
Simple things I take for granted on the PS4 like share a screenshot or upload a video to youtube I really miss on the Xbox 360.
Did not get a chance to play much else except the Destiny raid effort yesterday evening. I did watch the PS Experience Keynote on Saturday which was very impressive with lots of new games to look forward to in 2015.
