It means that Pico Park 2, much like the original game, is a “your mileage may vary” title depending on who joins you when you play. If you have a group of four people who can all be in the same room together, it might be absolutely incredible. Especially if they are all familiar with the series and experienced with how games like this work. If you’re only playing with one other person, it could still be great! But you won’t get the full experience and might be frustrated sometimes. I 100% suggest not playing this with random individuals. Even though the in-game messaging system is competent and I had a decent ping playing on the Switch against others, randos are a nightmare in Pico Park 2 and ruin the experience.
