City of Rott is the only GE game on Steam. There has been multiple iPhone / iPad games made with Game Editor that made it to the App Store, but I think most of them are not downloadable anymore because the developers have not paid their annual fee (99$ per year

).
Probably one of the biggest hits ever made with Game Editor was the fan-made Sonic the Hedgehog horror game called Sonic.exe that was based on a creepypasta. The game was even played by some very famous YouTubers. However, the game was popular mostly because it was something rather new - a sonic horror game. The game was quite lacking in terms of gameplay, not the greatest display of the capability of Game Editor. Later the developer went on and remade the game from scratch in Game Maker, and that's the version that you'd probably find nowadays if you search for it.
You can check the Showcase forum for some of the best games made with Game Editor:
viewforum.php?f=26Also, there used to be a page dedicated for listing complete games made with Game Editor on the main site, but as the site is currently broken following the SourceForge data center migration, you can't actually view that page anymore.
Here's a list of some of the best finished games made with Game Editor:

There's also quite a few finished games that just have been buried deep into the forum and are kind of forgotten by now. Without remembering their names they are pretty difficult to find.
Also, these demos of incomplete games show great quality made with Game Editor:

Sorry for some of the pictures being so big... I was too lazy to actually download, resize and upload them myself.
