So first let me start off by saying, I am not running or have anything to do with the management of this event. So please don't ask me questions, but with that said, A group of people on FB have created a Suikoden Day event. The Theme for this year is Suikoden IV.
Moreover, the event is having 3 contests with real Suikoden swag for prizes for 1st and 2nd place. The 3 contest include a fanfic contest, a cosplay contest, and an art competition. More information about the rules and the prizes can be seen on the website's post. It seemed pretty cool to me! Check it out!
