How do you feel about being repeatedly punched in the dick?

Oh boy, here we go. First, I meant that on multiple levels. Tarkov has some interesting dynamics with competition and dual classes of players, and competing incentives to both team up and betray others based on in-game tasks and rep systems. The high emphasis on looting (my understanding is it's like Rust but more) and penalties for dying (you lose what you brought in), make for tense interactions. They just added in-game VoIP this last wipe (late December. Every 6 months or so they wipe player status and make everyone start over along with a big patch to change some of the game, because it's still beta).

That's the player side. The other faith you'll lose is in the developers to fix your pet peeve bug, because while they make large gains and fix many things, other small things tend to be left for a long time that drive people crazy.

I've not played Rust, but from what I've seen of it and what people have commented, Tarkov is like Rust but more extreme and more realistic. Depending on why you liked Rust, you might downright love Tarkov, and it's already highly addictive, so maybe don't install it? It often feels like Dark Souls the looter FPS edition, because it's so, so rough sometimes.
