I tried out the Clocktower (awesome stage), and the Ghost Ship (beautiful-looking but not as awesome because some parts of the deck are obstructed by the ledges of the ship, making it hard for you to see any brawling that happens in there).
I fully tricked out my Brawl. I use that awesome blue character select screen, and have got almost all different stages (huzzah for bringing back Fourside, fans!).
