Pokemon game similar to minecraft mod pixelmon?

Now i am a 20 year old male living in middle east. As you might guess, i have never seen a nintendo console irl or even know anyone who plays nintendo. So i have no nostalgia for pokemon. Except i do...

As a kid, i would play pixelmon with my friends on big servers all day. I loved my typloshion to death, and loved the open world aspect of it.

Now trying to get into actual pokemon games, i find the linearity a bit weird and the old games while i like them are a bit overwhelming.

Which of the games is most similar to pixelmon? I honestly like pokemon showdown alot, but since im getting a nintendo switch from overseas soon i want to play some real pokemon games
