There are alternatives to c++ such as skookumscript. I personally am a fan of skookum but it has a learning curve (depending on your programming background) and some rough edges.
You can use blueprints and then move the complicated parts to c++ or skookum. I personally feel Unreal is an easier engine with skookum for game logic and blueprints for basic configuration, but everyone has their own opinion and valid reasons for one engine or the other.
