In previous games, players could hog a stage's edge, preventing opponents from making a return, but it looks as though this has changed. In the picture, we can see Link grabbing for a ledge while Mario looks to be getting repelled. "There are many changes being made to attack and defense options for grabbing edges," game director Masahiro Sakurai wrote. "In this picture, Link is actually trumping Mario's grab."
Sakurai noted a few other changes as well. Air time and accumulated damage will determine a player's period of invincibility while hanging on an edge, and grab controls will no longer be affected by damage being above or below 100 percent. This may all sound like nitpicky things to fuss over, but details like these can make or break a fighting game's balance. Besides, you'll probably appreciate it when you're the one clawing desperately back onto a ledge.
