I started with tutorials for game creators at the end of 2016. The games I created with these tutorials are accesable through this page. Through these tutorials I found Unity to be the creator of my preference so look forward for more on unity
ClickFusion is an relative easy way to create games. The programming is done through easy point and click interfaces and is primarely used for 2d games
GamemMaker is a little bit harder and has its own programming language. This creator is also primarely used for 2d games
Unity3d is one of the best known creators. It is used for 2d and 3d and uses C# scripting.
