Dragon's Dogma: Dark Arisen

Hard mode in this game is no joke. Enemies have huge health pools and deal a ridiculous amount of damage. A swarm of bats can kill you in a few hits, and most large enemies will one-shot you. As I mentioned in the Road Map, do not attempt this difficulty unless you have two high-level pawns to recruit off your friends list, or on your second playthrough after leveling up your main character quite a bit. The game only needs to be completed, so if you did a full playthrough on another difficulty first and you're doing this in NG+ you can just do the main story only.
