In my opinion do this once a year so I can go next year~
Memories of BBG is what keeps me playing melty to this day. It's an excellent opportunity to bring new players into the scene as well, so get on that.
Wish I could go, record all the matches, take video of the event, and lots of pictures. If so I can make a video and share the stuff with JP Melty community as well.
If you can find a way to stream this I want to have some players over my place and JP Restream the event
