You say that as if any of those games or series are truly original:

Fortnite

Fortnite just copied other survival games like Rust and Ark. Epic put their own spin on it by combining it with a battle royale - sorry, with a PUBG game mode.

Zelda

If you’re talking BoTW and ToTK, you can argue they just copied other open-world games like The Elder Scrolls and Far Cry and added a Zelda flair. Weapon degradation was even present in the older TES games.

Pokemon

Pokemon is just a kid-friendly version of the Shin Megami Tensei games without the fusion mechanic. Some of the Gen 1 Pokemon designs were also more or less lifted straight from Dragon Quest.

Minecraft

It was more or less virtual Legos when it first came out, and the survival mechanics gave it a unique spin.

So if you really wanted to, you can reduce all of the games you mentioned into their influences and what they straight-up copied. Funny thing is, these are all very well-received games because their core gameplay mechanics and designs were very good, and they added their own spin on things. Copying others isn’t a bad thing so long as you’re either iterating on it to improve it or to do something different to it somehow.
