I've searched the forum for a thread on this,and haven't found any. So what's the most challenging/toughest game you have played? One house rule,a game that's tough and challenging based on its content,not because of crappy gameplay etc! Toughest game I have ever played is The Witness. A puzzle game,looks stunning and by far the hardest game I've ever played! Ps if I missed when I searched for a thread on this subject,feel free to erase!
