Your statement is just not correct.
You claim you can only make very limited games without editing, adding or rewrite the code. That is not true, it is the opposite. Without coding anything at all you can achieve very complex and advanced games. Actually I think there is just a few persons who actually ever code anything at all to get the things they want, that is not supported.
And if you do not know any coding, I honestly do not think you will need to do it for your game. From your bullshit comments I would guess your game would not be that advanced.......
What exactly do you want to build that you claim is impossible?
Also... You could just have downloaded the software and used it for free, before you decided to buy it....
