At today's (well, yesterday's) Square-Enix presentation at NicoNico Chokaigi, there was this particularly intriguing video showing a fight between characters Yda and Livia sas Junius that sort of resembles something you may find in Street Fighter.
Unfortunately, this was just for fun and there are no actual plans to implement something like this in the game. But why waste such a good idea? Now they've opened up Pandora's Box and everyone will be demanding this.
So what do you guys reckon? A good next step for Gold Saucer? Or would SE duck from the idea of making a game within a game so engrossing that no one would be running dungeons?
