Damn, so much bullshit in a single post.
Really? Let's see.
The Twist and The Twist 2 are basically the same game... same incest concept as every other game here. Same giraffe-looking models etc.
Incest concept? No. That's a type of content. This is like saying that a soviet truck from the battle of Staligrad is the same as a modern truck because they both carry crates of potatoes.
I don't really care about the content here. To be quite honest, I find it annoying. I care about the technology behind it and business aspects (niche business, unknown type of gaming etc...)
Take other games from this website and try to zoom in and out, try to change camera angle. And you will see what I'm talking about.
Most games here are just pictures, annoying music. When they get all worked up and ready to give some content... You get a GIF level animation. Just ridiculous if you want my opinion.
Complex game engine? He use a pre-build engine in Unity and isn't able to optimize it in any way. The Twist 2 will be more hardware demanding than The Twist. If he wants to make a "real" game then he should go back and start to learn how to code.
Look at this thread. Many are complaining about the time between updates. And you want KST to spend 20years coding a new game engine? Why not ask KST to reinvent fire and reinvent the wheel while at it?
Unity is a toolset already available. And it's a powerful one at that. You can do amazing things with Unity.
So, you are a right, it's demanding and poorly optimized. But that's obvious. But look at the evolution from The Twist to The Twist 2. There is room for improvement.
While the other games... I don't see them adding different content. All they can do is add more pictures. More of the same.
Do you know many games where you can move the camera? Do you know many games where you can customize characters?
I tried the games one by one looking for ideas. And all I saw was disappointment. Some games were even made with RPG maker. Still, pictures, pictures, awful grind...
In fact, I saw more talent in the work of the modders that added cheats than in the original games. Just a terrible situation.
And then KST did something ambitious with The Twist.
