Aka the spiritual successors to demons souls on the ps3 aka games where even the best players will die a lot.
These are adventure/rpgs where an oldschool mindset is needed. A lot of planning is necessary just about everywhere. You need to make every attack count. You rarely run as that can easily lead to your death. Death is just a learning experience in these games, you will die a lot but if you learn from what you did wrong you can survive them.
These games aren't the hardest but you need to play them like a survival horror title where you need to be aware of your surroundings at all times and NOT treat the combat like it is dynasty warriors.
Also, not for those who hate occult themes in games but you could probably tell that from the title.
