I'm making an entire week of Smash 3DS, literally. I've got it all planned out with my mate, time off work, everything.
First off, I'm most likely gonna spend 1-2 hours in the lab with Rosalina. Then me and my mate will most likely do a Smash Run, to get an overall feel of the physics of the game, without worrying about fighting AI that know what they're doing, while we're getting used to the pace change.
After that, who knows? I've got a week of solid Smash and nothing else and I intend to use it well.
