Its not often game developers give away games for free, but XSEED are giving away their PSP game Valhalla Knights for free on the US PlayStation Network, here is some information from Wikipedia:
In a realm forgotten by history, humans, elves, halflings and other assorted races lived together in harmony in an untainted paradise surrounded by thick green forests and crystal clear streams. However, this tranquility was abruptly shattered by the roar of demons as the Dark Lord returned to reclaim his throne as the ruler of these lands. This set off a series of bloody battles as all races become ensnared in the violent conflict.
After years of fierce fighting, the Dark Lord was eventually sealed away by the hands of as hero named Rulzult. However, the damage had been done. All the demon blood spilled during the war caused the land to become cursed and the sky lost its light. This once serene paradise became known as “the Cursed Land.” It entrapped its inhabitants and filled them with despair, causing each waking moment to feel like an eternity.
One day, a brave youth awakens in this land, unable to recall who he/she is and having no recollection of his/her past. The story continues, following the unknown youth on a journey of discovery to find his/her lost memories and determine the future of this forsaken land.
The player fights against monsters to obtain new items and equipment. Five races are available for your character: human, dwarf, halfling, elf, and machine. Additionally, four initial job classes are available—Fighter, Mage, Priest, and Thief. Additional job classes can be acquired through job cards dropped by monsters in certain areas; these include Anchor, Knight, Samurai, and Ninja. At any time, each character may pick up to two job subclasses in addition to their main job class, and certain attributes of that subclass will carry over into gameplay (such as a Fighter being able to cast spells with a Mage or Priest subclass). Actions during combat will change depending on the weapons equipped, and each of the numerous weapon types is only equipable to a certain subset of job classes. After building up a gauge through combat actions, a character can perform a special attack. Different special attacks can be performed when equipping different weapons.
