Clickteam fusion 2.5 has made games only game maker studio 1 and 2 users could dream of making, it has made chat boxes, docks, 3d games, games that use the Nuerosky mindwave headset all without code, even RPGs and platforming games and match 3 games and games like Tetris. Not to mention clickteam fusion 3.0 is on its way allowing export to all consoles including the switch and html5 and flash and Xbox and PlayStation and iOS and Mac and Linux and android.
What is a dock?
Also, the quality of a game depends mainly on the quality of it's atmosphere. Meaning, art assets are very important.
Game maker is not a bad option, because it allows you to tweak the feel of the game, using maths and code. Fixed Engines like "make a game with no code" are fixed engines, you cannot tweak the feel of the game. The other thing is lag. As long as Game Maker has no lag, you are fine. If you think it is hard to code in Game Maker, try C++ or C#, they are much harder to code, yet lots of money is being made by C++ C#. Coding is your friend not enemy. Customization is your friend not enemy.
You can patent them as patents are for inventions. You can't patent a concept as a concept doesn't exist. Copyrights are something different that dictionary defines: the exclusive legal right, given to an originator or an assignee to print, publish, perform, film, or record literary, artistic, or musical material, and to authorize others to do the same.
Here are some patents in gaming:
Sega had a lot of patents including an overhead arrow guiding you to your destination and the ability to transition a camera from trailing your car to being in your car rather than snapping from one to the other. Midway has a patent on ghost cars with time trials. I think the Dynasty Warriors game has some odd patent on fighting more than 5 enemies at once. There's a patent on having a game on a loading screen. EA has the patent on the dialog wheel. Tetris is protected.
I dont think any judge recognizes those patents because I see lots of Tetris clones and games with more than 5 enemies fighting you. I also see Mario Kart has ghost cars and time trials yet was never sued. The overhead arrow is not even an original invention, it is stolen from a compass. Those are ridiculous patents a bit like trying to patent the ingredients of a game. They are common components featured in common games. It would be a bit like someone trying to patent a lemon, instead of trying to patent their lemon cake recipe. Also, I don't think camera movement can be patented, or else photographers and movie directors would be suing other photographers and directors for filming movies at a certain angle. Wanting to make money isn't bad, but there comes a point to where greed consumes you and removes your humanity.
