Demon's Soulsis an open-ended dark fantasy action RPG. Players are able to customize their own characters, setting the name, gender, hair style and other characteristics. Players face off against huge beasts many times the size of the character, making use of a variety of different weapons. The gameplay alters depending on what type of weapon the player wields. When utilizing bow and arrow the camera enters a close over-the-shoulder view. There are also various forms of magic that can be used in a defensive or offensive manner.

This is, in my opinion, the best game out in the PS3 right now. The game basically resembles how Monster Hunter plays, Basically, you can equip armors and it changes your appearance. You can use different equipment with different sizes(some are just plain huge).
