I thought it was already on Twitch. I could have sworn it was listed as Project M during APEX. Of course, there was so much Smash at APEX, it was hard to keep up with them all. I missed most of Smash 64, but I caught most of Melee, PM Top 8, and various bits of Brawl. Fun stuff to watch. Kage Vs. MattDotZeb rematch. Hype.
During Apex, they usually set the game to either Melee or Brawl while Project M was happening.
