I thought it was kind of interesting that they chose to use only the original Toriyama artwork instead of the newer TOEI character portraits. *crosses fingers for new anime and/or "manga" sequences*
As for the multi-player...I'm sure the Millennial Fair will be expanded...Maybe Lucca will have other robots to fight! Or Norstein Beckler will have more creepy crap for you to do. Maybe the concert stage will let you play music from the game (seems reasonable enough, right?). I always thought it was kind of a small fairgrounds to celebrate 1000 years...>_>
