Need some opinions on the quality of these games

First of all, I'd like to start by saying I am new some new games. I recently cashed out of TF2, and now I only really play GTAV and Payday. I need some new games to play and it seems like most people here are pretty well versed and knowledgeable about quality stuff.
Good genres in general
- Crime / Heist
- FPS
- Open World
Basically describes the games I like playing the most, GTAV and Payday. But I am also looking at these games, and want to know if they are good or if you guys know.
- ARK: Survival Evolved
- The entire Battlefield series/entries since I have never played a Battlefield game except the BF4 Beta on Xbox 360.
- Rust
- Interstellar Marines
- KILLING FLOOR 2
- I already have CSGO, don't even mention it here
I am only asking these questions here since I feel like the people here are generally smart and friendly, and usually well versed and intelligent. I just want some of your opinions on the best games out there on the market right now.

Killing Floor 2 is really good so far, just lacking content at the moment. But it's receiving pretty big updates. Core gameplay is essentially done and pretty well-polished too (the final boss is slightly imbalanced when playing with 3 players or less though).
