Last night I was playing Super Smash Bros. Ultimate online and trying to improve my Corrin (a Fire Emblem character) game when it happened. A Donkey Kong was floating above me, just out of my reach, and I prepared to strike as they landed. The timing needed to be precise, but the game froze for a full five seconds. When it smoothed out, Donkey Kong was on the other side of the stage and my poor Corrin was punching at air.

That’s the sorry state of Super Smash Bros. Ultimate right now—it’s an almost perfect game, everything I ever wanted out of the series, with a terrible online mode. The lag problem is bad but it’s not the only issue. Those who want to compete online have to navigate obtuse systems and wait in line for their preferred match, only to end up in a game type they didn’t want. It’s a shame, because Super Smash Bros. Ultimate is best the franchise has ever been.
