Finally (Firstly?), I’ll start with a topic which I love so much: Horror games.

"love" is already a pretty strong verb, so "so much" feels a little redundant and as a result, unnatural, here.

Finally seems a little odd for the first point.

I started thisenjoying these when I was just a kid, around my 11/12/13 years, (yes I know this is too early,) but even at this time, I already had encountact withered horror games like Resident Evil.

Since you haven't mentioned an action yet, "this" is a little unclear.

"had contact" sounds a little robotic here, so changed to "encountered" for done.

You had a lot of comma seperated thoughts here, so I changed one which is more of a side comment to be parenthesised to make it read a little better.

The problem is, I didn't know anything in English, barely read, felt lost muchtoo easily and then I gave up.

Starting my adolescence, youtube was already a phenomenon, with a lot of content creators and every type of videos to watch.

"every type of" takes a singular noun afterwards.

I always liked to watch videos, mainly about the games, such as watching videos from my favorite youtubers playing horror games which I didn't have anythe courage to play,. This showed me that I was passionate for horror games, just nodidn't have the bravery to play haha.

Again, there's a lot of comma seperated points here, it's clearer to just break it into two sentences.

Analog horror, psychological horror, survival, games, videos, and movies, the creativity involved always captivated me, mainly if it involvesd monsters.

"involved" to match the tense of "captivated"

Jumping (forward) to the current era, with myhere I am 19 years old, I always play every game, about horror, as far such as survival Hhorror games, Resident Evil, psychological horror games, Silent Hill, but o. Oddly enough, Outlast 1 it’s my favorite game about horror, not the franchise, but youtheir purpose to be a really scary horror.

I think you thought it was "jumping for" because you might have heard "jumping forward". I'd guessing people are 50/50 for whether they'd include "forward" in this sentence or not, both work fine.

In some other languages you "have X years" to describe your age, but in English you are "X years old". In casual speech, you can drop "years old", but you have to either include both words or neither word.

"about horror" doesn't work as a clause on its own, so removed the comma separating it from "play ever game"

Putting you into athe skin tof Miles Upshur, a freelance journalist who receives anonymous denouncing about the strange events in Mount Massive.

The noun of "denounce" is "denunciation" but I think that's not the right noun here. It doesn't quite fit within the context.

Miles, doesn't have any weapon, or knows how to fight, it’s only you and the unknowns.

Again "Miles" is not enough of a clause to be seperated by a comma like this.

With this purporemise, this game shows me the major physical horror that I have been faced with, it's a sick game, I recommend it if you are as in love with horror as me.

"sick" as an adjective with a positive meaning is both a little dated (more likely to be used by people in their 30s than 19 year olds, I think), and more casual than the rest of this piece has been written.

But in your opinionas for you, do you like horror?

This is a little nuanced, but you wouldn't ask someone if they like something in their opinion. That's because "in your opinion" is for something where you're asking the other person for an answer with an understanding that they might have uncertainty about the answer they give. However, when it comes to if they like something or not, the default assumption is they will know the correct answer.
