Nexon's Irish mythology informed massively multiplayer online game Mabinogi has inspired some comparisons to Sword Art Online. So, appropriately, following all of Nexon's Magi crossovers, between August 15th and September 12, players will be able to get SAO based avatars, costumes, weapons and even working Alfheim Online works.

What do you guys think? I'm going to play this game just for the SAO crossover.
