Yes, I preach to you guys about not making threads about Dojo updates. Yes, this thread does revolve around a picture shown in today's update. Yes, I do think this topic deserves its own thread.
In today's (10-31) update, a picture is presented to us showing a jack-o-lantern laying on the ground:
Just incase anyone needs reminded, today is Halloween. Having said that, its fairly obvious (to me, anyway) that this item would not appear on the stage every single time you play the game. If this is the case, it seems apparent that Sakurai is really taking advantage of the Wii's internal clock.
Think of the possobilities. Not only would items be put on a stage during a special day, perhaps they could take it a step further?
Character Costumes: Who wouldn't want to play as Santa Snake? How about Fox wearing an easter bunny costume?
Event Mode Matches: Assuming that Event Mode will return, this could easily be incorporated. Again, these would only be available for one day.
One Day Only Give-Aways:These are very common among other games, particularly MMORPG's (ever play runescape?). You would be given a surprise item simply by turning Brawl on during a special day. Show off your dedication to Smash by using or wearing these rare items. This would be one of the only things I can think of that may remain after the 'special day' is over.
Special Occasion Stickers/Trophies: This seems like by far the most probable thing that will happen out of anything thats been suggested. Stickers could be given to a person for logging onto their profile during a special day. Inspired by Paulpro.
I will edit this post as more ideas surface. Post away!
