Super Smash Bros. Ultimate will ditch the “For Fun” and “For Glory” matchmaking types and group online competitors according to new systems, including preferred rules and a ranking called Global Smash Power.
Director Masahiro Sakurai outlined the new features in this morning’s Super Smash Bros. Ultimate Direct. Broadly speaking, users may set and change their preferred rules for online play. The matchmaking system will then attempt to group as many people with similar preferences together, and then randomly select one fighter’s set as the rules for that match.
