PICO PARK Guide

Sources & Editorial Policy

An independent fan resource. Sources were checked on 2026-11-12; pages are updated when official material changes.

Four kinds of evidence

The official portal (picoparkgame.com, English and Japanese) and official Sega announcement pages are primary sources for the games' identity, rosters and release framing. Store listings — Steam, the US Nintendo eShop, the PlayStation Store and the Xbox Store — are primary for prices, dates, requirements and feature flags. Wikipedia is a secondary encyclopedia source, used for the PICO PARK world-set names. Achievement trackers (Steam's own global percentages, TrueAchievements) and media guides (Gamepur) are attributed secondary sources. The two Fandom wikis (pico-park.fandom.com and sonic.fandom.com) are community-edited: their claims are attributed and marked *(not yet verified)* unless an official source supports them.

How disputes are handled

When sources disagree, this wiki shows both positions instead of picking one. Current examples: PICO PARK's official date of June 8, 2019 against Steam's May 7, 2021; PICO PARK 2's official August 28, 2024 against Steam's September 12, 2024; the official three game modes against the community wiki's "five gamemodes"; Steam's sale prices against list prices on every game; the Gemdrops, Inc. developer credit that appears on Steam only; Wikipedia's "Ball park" against the wiki's "Ball game" for the same PICO PARK set; Steam naming the SONIC PICO PARK World 7 achievement LARGE PARK while TrueAchievements' Xbox list calls it BIG PARK; the official SONIC PICO PARK ESRB RP badge against the PlayStation listing's ESRB_EVERYONE field; the official site's Windows/Steam platforms against the Steam listing's macOS build; and Gamepur's pre-release article that called the Steam page "not yet available" and treated PC as Windows-only.

Numbers this site will not invent

No stage names, per-world stage counts, puzzle solutions, battle-rule names, endless-variation names, PICO PARK 2 level names, character moves, review counts, historical player peaks, wishlists, patch notes or version numbers appear without a source. The 512-player figure is a dated point-in-time sample from Steam's API, never presented as a peak. Launch-day achievement percentages are always dated and expected to drift.

Snapshot dating

All sources were read on 2026-11-12, launch day of SONIC PICO PARK. Live numbers (global achievement percentages, store prices, ratings, player counts) reflect that snapshot and will change as the games and their stores update.
