I have not heard of Adventure Maker, but it looks like the latest version supports Windows 8, so color me impressed.

AGS is by far the standard for point and click (lots of commercial releases). There's also Adventure Creator for Unity.

I've only used the Phaser javascript library directly, not the editor.

I mostly make point-and-click adventure games with Adventure Game Studio, which is free and has an easy learning curve. I've also used RPG Maker, Unity, and PhaserJS. Haven't used them, but I've read good things about Godot and Game Maker.
