Ouu yes
I never played some of them, so I"ll take a look on it. You' re great, thanks. 
It's little bit hard to say. I was making racing game in Blender Game Engine. I know, it uses a Python scripts, so it is not "professional". But I was eleven. After some years, I started to program my own game engine, because BGE didn't fit my needs. I was programming it for two years ( I started with Opengl + C++ and then I switched to Vulkan, but I neved finished it ). I really liked this time but I wasn't making a game but GE. I switched to unreal. I made some prototypes and all the stuff. Then I started to lead small team of my classmates and we started make games. But, here's the problem. We never released game. It is becacause I was 16 and I didn't know how to do it. Now, we are all 18 and we want to choose the right genre to be successful. I think this is good for us but I don't want to let it only on me. That's why I came here
Okay, I think that I explained it a little bit wrong. Just imagine witcher but with divided into small one or two hour long episodes just to keep it exciting. Smaller episodes are easier and faster to make but I don't know how would be the interest about this type of game.
I didn't mean that you need realistic graphics, but it needs to look good. Don't underestimate how much work it is to make good pixelated graphics.
I don't think that art will be problem. But story can be. We actually have basic ideas and plots and we wrote some scripts. The problem is with translation into English. I don't think that translation would be as good as native speaker's English.
It's probably a good idea to write the story in your native language first and then translate it. Either yourself or by paying a professional, if necessary.
