Many Construct 2 developed games are on Steam, and one of them was even reviewed by GameInformer, the #1 video game magazine in the world.

The review was right next to the review for The Last of Us DLC, a game which won over 200 industry awards.
Construct 2 is a serious development tool. If you're looking for a huge portfolio of popular games like GameMaker, you'll have to wait because that took many years to develop.
Personally, Construct 2 is my favorite game development engine, and I've used many (Unreal Development Kit, Unreal Engine 4, Unity, GameMaker Studio, MMF2/2.5, Stencyl, GameSalad). It's the fastest prototyping tool around (try using it in a game jam) and the interface allows for a lot of customization. Scirra also has the best forum for a game engine I've ever used. Maybe you should try other lesser game engines to fully appreciate the capabilities of Construct 2.
