2,000 hour review - The game is fun, but still early on in terms of progress. Hopefully they will release updates in which will further the games performance, LoD, and other factors...
They have had zombies, and gameplay is very trivial. The graphics are what they should be for a game like this. Pure Survival. Getting knocked down doesn't feel like a daunting task, more of a welcoming challenge. It's balanced, and fun.

4,000 hour review, I have created my own Rust Community through Discord which you can locate here - https://www.discord.gg/uezW48Z I have started hosting my own servers, and have created quite a few friends along the way. Running a server is so far, one of my favorite aspects of this game. The things you can do outside of normal gameplay, or mod into your own server are among one of the most entertaining things you can think of. Including Flying.
The annoying scream you receive when you go down, is gone. Thank GOD.

They have released a standardized spray pattern much like the AK in CS:GO that many of you may know. I'm still not decided on whether this is a good implementation, or a bad one. Many are saying they disagree with this change and that it is bad.

In addition to this, they have patched the ability to build under or near monuments such as Satellite Dish. They have changed the look of the Kilt, which I like. It's a nice change.

7,000 hour review - I've stopped hosting, the game is still entertaining and they have released Frog Boots, Helicopters, and Boats. Performance has seen a small to decent increase.

10,000 hour review - I've taken a small hiatus, and am getting back into the game. They have added things like Oil Rigs, a Larger Helicopter, fixed many textures and bugs, and the game is still doing well many years later in terms of population. It's great to see this game thrive. If you read all of this, I'd recommend buying this game for purely the fact that it's had countless numbers of updates, once every month matter of fact and I love the gameplay.
