Escape from Tarkov is a really unique one. I kept trying to play it like PUBG and just got destroyed by the AI and other players. Once I slowed and treated it a little more like Arma 3 it was a lot less brutal. But there are still players that are so good they'll really punish you for silly little mistakes. I typically don't use any of the mobile games aside from some puzzle or word games so I haven't tried that Rules of Survival. Either way, there are a few people that stream Escape from Tarkov that a really informative to watch.
