Thousand Arms

The Dark Acolytes, a mysterious organization of cyborgs and robots, is trying to find the five legendary Sacred Flames, and bring chaos to the World in the process. Meis, a womanizing "Spirit Blacksmith" with the ability to make magical weapons, finds himself chosen to find the flames before the Dark Acolytes do. However, to increase the power of his weapons, Meis must have the help of a woman, and must increase his 'intimacy level' with her by going out on dates. Along his journey, he meets a colorful cast of characters, including girls to date and heroes who join his party.

Combat in Thousand Arms is turn based, with up to three party members to be taken into battle at once. However, only the front character is actually able to physically attack the enemy. The other two characters serve in a supporting role, taunting the enemy and utilizing certain items or spells (the enemies have the same limitations.) If necessary, characters can be rotated out such that one of the support characters and the lead character exchange position

The key feature in this game which distinguishes it from most other RPGs is its built-in mini-dating simulation. Thousand Arms' dating sim features dating locations in many of its major cities and towns, and a cast of nine women. The dating aspect allows the player to pick dialogue choices.
The dating aspect also has an actual in-game effect. By successfully wooing each female, her intimacy level can be slowly raised. As this level rises, it grants her the ability to imbue weapons with increasingly powerful spells and skills. This magical forging, which is possible due to Meis' training as a Spirit Blacksmith, relies on the smith having established such positive female relationships.
