Wakfu contains various Social aspects so that players can interact in unique ways.
One of the first social interactions is deciding on a Nation to join. Wakfu is a sand-box style game, which means the social obligation is up to each individual player. There are various Laws set by Governors which can also affect the game. Citizenship Points are rewarded to players who contribute to their Nation or an allied Nation.
Another major point of the social aspect are Guilds. These can be created by any player.
Marketplaces are the center of trade on each bridge in each Nation. Many players gather here to chat, duel or sell items.
Emotes allow the character to do special actions and can be quite entertaining depending on what's used.
The Haven Bag can hold a private gathering of friends, or just show off instead.
Keep track of friends (and enemies?).
