Mabinogi

This is a fantasy MMORPG based on the Celtic mythology, Mabinogion. Unlike other games, when a player starts off in-game they may choose an age for their character instead of a class. For every Saturday that passes, the character will age one year and as a result they will recieve higher level-up stats and such. A unique feature in this game is the rebirthing of characters. You can choose to rebirth your character back to level one (resetting everything) except the skills you have learned in your previous life. By rebirthing you will be able to have more skills than a player who does not choose to rebirth.

This fantasy role-playing game pits your character against the entire world of Mabinogi, Erinn, where you can choose to pursue monsters, quests and money, or just develop the ability to make amazing items.

Characters are created by using Character Cards (additional cards must be purchased from the game service store). There are two kinds of cards, basic and premium (a newly created account has one free basic card). Premium cards give the player a wider variety of hairstyles, eye and mouth shapes and also come with more elaborate clothes than the basic type. When creating a character, one may choose an age between 10 years and 17 years-old. The character will advance one year in age every (real) Saturday.

Different ages yield different initial stats and affect the amount of stats raised in a Level-Up. Rebirthing is one important factor of the game. One can choose to use a Character Card for rebirthing one of their characters instead of creating new one. Rebirthing allows the player to change the character's gender/age/appearance and reset the character's level back to 1 while keeping character's previously gained skills. As it gets gradually harder to gain more levels as your level becomes higher, and since all skills require a great amount of Ability Points (see below) at a higher rank, there's a limit to character improvement if you don't take advantage of rebirthing.
Performing different tasks and eating different kinds of foods changes the appearance of the characters. It may change their body shape and may also raise/lower some of their stats.

Players may play music composed by other players using musical instruments. Each (real world) day of the week grants players specific bonuses, such as getting a higher experience rate for certain skills, higher item creation success, aging, gaining AP, etc. The game is now at the Generation 5 stage, which added a whole new breed for players to choose from, the Elves.
