So you've bought Pico Park and noticed there's no one online to play the game with.
Here's a step by step method on finding players.

Step 1: See there's a guide that just goats people into playing Pico Park with someone and notice it's a year old post.
Step 2: Rip off the idea and start a new guide with a more honest title like "How to find players to play Pico Park". Try and work in some timing, like doing this during the Steam Summer Sale of 2022.
Step 3: Mention that people should comment on your guide if they want to play Pico Park with a group, so players are gathered in one spot. (comment on this guide if you want to play the game with a group)
Step 4: Wait.
Step 5: Get people to play the game together with you while also collecting rewards for an excellent guide.
Step 7: Offer your bank credentials to Lord Gaben and/or gift me games, because it's Steam Sale.
