A really well done article using the current Guilty Gear Strive beta as the focus.
Online fighting games during COVID: How rollback helps us connect

I watched a match between fighting-game commentator and streamer Sajam, who is in Long Beach, California, and Footsies developer HiFight who lives in Japan. The ping stayed a steady 124ms, and the rollback frames never went higher than 3. The matches on Sajam's end looked very smooth. We'll see more reports as the beta opens to more people, but the early word seems consistent, Arc System Works did the netcode right.
