Despite the fever at theit being so popular at launch, It felt like no one besides me was playing the game in my rural smalsmall rural town.

And local players started to come to the park when events awere ongoing.

Careful of tense

More and more people started to come to the park to get an invitation for the EXraid.

And last month, they finally allowed Pokemon GO players to submit a POIhe ability to submit their own POI which allows them to create a new pokestop.

Being in a rural town helps the submissions go throughet approved faster.

The parking was full and I saw more than 20 people playing the game despite it wasthe freezing cold and raining.

This sounded more natural to me

My hard work of 2 years tot2 years of hard work finally paid off today and, so this was my success story.

Pokemon GO: Making a hot spot in my rural town

Despite the fever at thehype at launch, It felt like no one besides me was playing the game in my rural smalsmall rural town.

I edited a nearby park last year on a website called Open Street Map, which is where Pokemon Go extracts the map data from for various uses.

A few months later, the said park became what's called a nest, making it a great spot to play the game.

And lLocal players started to come to the park when events are ongoingthere were events.

This year, the park became eligible for EX raids, which gives you a chance at catching a rare legendary Pokemon if you win the battle.

The parking lot was full, and I saw more than 20 people playing the game dein spite of the fact that it was cold and raining.

We won the battle with ease, and I caught a Regigigas, an EX raid exclusive legendary Pokemon.

My hard work of 2 yearstwo years of hard work totally paid off today and so t. This was my success story.

I've been playing Pokemon GO since the launch.

You could also say "since its launch". "Since the launch" is technically correct, but these feel more natural to me.

Despite the fever at theish reception at launch, Iit felt like no one besides me wasI was the only one playing the game in my rural small town.

There are lots of ways you could say this, so I picked one that kept the 'fever' part. "Despite it being so popular at" and "despite the hype at" both work too! For the second part, "no one besides me" works, but "I was the only one" would probably be my pick. "No one other than me" would also work here. :)

A few months later, the said park became what's called a nest, making it a great spot to play the game.

"The park" also works, just letting you know that you can also say "said park" here, since you just talked about the park in the previous sentence.

I've successfully created more than 10ten new pokestops in my town since then, including 2two in the park.

You don’t need a capital letter after a comma =)

A few months later, the said park became what's called a “nest”, making it a great spot to play the game.

Or you could remove “the”, so that it reads “A few months later, said park became...”. This would be a more old fashioned / formal way of writing, and certainly I’ve never heard someone speak this way, but it would be correct.

And lLast month, they finally allowed Pokemon GO players to submit a POI to create a new pokestop.

Teachers at schools in England tell us not to write “and” at the start of a sentence (because it is a conjunction, which connects two halves of a single sentence together). Plenty of people speak like this with friends, but it looks a little strange written, and it’s not really necessary.

The parking was full and I saw more than 20 people playing the game despite the fact that it was cold and raining.

Did you mean the park itself or the place where people park their cars or bikes before going into the park? The “parking” is the place to stop your car.
There are a few different ways to correct “despite it was cold and raining”. You should say “despite the fact that...” or “even though...” or “despite the cold and the rain.”
