FFXIII. Despite how much hate I give it, I do give all FFs that I own a good try. Unfortunately, once I got to the final boss, I couldn't do it. I thought to myself "why am I still playing this game when I can play a better game?"
Far Cry 4 and other similar Ubisoft games like Assassins Creed I could never really get into despite liking set pieces and foreign environments.
