QT

QT launched on January 23, 2020 and received a substantial run of post-launch updates. The developer shipped two named major updates during 2020-2021: Update 2.0 on June 25, 2020 (which overhauled the QT portion of the game with new art and gameplay), and the QT Summer Update (2.5) on July 8, 2021, which added seasonal content, new friends, and new areas across all three games. In between, several smaller feature patches and bug-fix updates were released, including performance improvements and achievement tweaks. The Summer Update on July 8, 2021 is the last major content release on record, and the developer's post history shows no major content, announcements, or developer communications after that date. There is one note of interest: an update post from May 2020 mentioned a "4th game" that was in progress at the time, and the news scan flags one announcement post teasing a 4th game — however, no subsequent developer communication has confirmed this is still planned or in development, and no unreleased DLC is listed on the store. The only DLC (the soundtrack) was released on April 10, 2020. Given the last developer communication was July 8, 2021, and no content has shipped or been announced since, the game appears to have reached its complete state with the Summer Update. The developer has not explicitly stated the game is finished, but the absence of any communication or content since July 8, 2021 — nearly five years ago — combined with no outstanding commitments or unreleased DLC strongly indicates development has concluded.
