The tactical shooter aspects of Rainbow Six all but died after Ubisoft bought Red Storm Entertainment. After R6 Rogue Spear, the series started morphing into a bog standard run and gun shooter.
My friends and I played R6 a lot until early 2020. It was a lot of fun back then. I preferred it over CSGO because it had more strategic depth and it didn't rely too much on aim. It was all about information gathering and learning different setups and countering the common ones.
Trying the game again last year and it was a mess. So many new operators to grind out for and a lot of them were really weird. We thought Oryx was weird already and now I come back and you can play as two robots as a single operator :/
