Advantages: Updates are interesting, the developers really try, the administration is also okay.
Disadvantages: There is no RP on it, people don't try to play it. It's not RP, but RPG.

I came to the project itself about 2 years ago. At that time somehow found out and decided to try. In the beginning there is a bot Jeremy or Frederico, from whom you need to take quests. After that other quest characters appear. I'll be honest, the quests are interesting, but sometimes there are difficulties, like with the quest "Enough hard work!" (I don't remember the exact name of the quest, maybe differently). In this quest you need to deliver pizza on special mopeds. Why is it difficult? On new servers there is ANARCHY over these mopeds.

Well, let's move on to something else. Updates are not very frequent, but they are interesting. But there was one time during the Valentine's update the servers just couldn't work properly. After that they of course solved this problem and gave compensation, but still, it's unpleasant.
The administration... Well, I'll be honest, the administration is still good, although sometimes it's so-so.

And now I want to move on to the main problem of Arizona RP. And this problem: RP practically DOESN'T EXIST. And I'll give some evidence: 1. In a recent small update they added "Streamer Mode". Its feature is that you can even harass a YouTuber, teleport to him. And here lies the essence. Imagine in the real world other people will appear out of nowhere and MG (RP term: MG means talking about real life, which can damage the RP process). Or imagine that a person will be turned into a deer or a chicken. Agree, weird. And secondly... And secondly I recommend watching the YouTuber DENER. He films on another project, namely Trinity RP. Well so. Recently he uploaded videos like: FIRST TIME ON ARIZONA RP — THIS IS A COMPLETE FAILURE GTA SAMP, PASSED AND COMPARED QUESTS ARIZONA vs TRINITY! in GTA SAMP, and also RP ON ARIZONA — MY FIRST GOV FRACTION GTA SAMP. And if you watch these videos, you can deduce 2 more minuses: 1. Even people in government fractions, where you can't pass an interview without RP practically constantly MG, and for people who play there, it's normal. And 2. Accessories. Go to Arizona and look at CR (Central Market). And with 100% chance you will notice a strange accessory on a person. Imagine people walking in the real world with halos made of donuts and with balloons that can turn into a giant in a few seconds. Again, weird. At the same time, the project itself writes RP for itself, although RPG fits better here. In short, if you want to play RP and interact with players, then I recommend Trinity, and if you are ready to play serious RP, then you should go to Gambit.
Conclusion: Arizona RP is an interesting project, it has great updates, but if you want to play RP, then you can easily bypass this project
