R6 Siege is the best Clancy game by a mile, despite the fact that they've gone pretty goofy with the new characters over the years.
I loved the original R6 and Rogue Spear back in the day. Played the shit out of the co-op especially on LAN in college... but let's face it, as cool as the plan a counter terrorism operation gameplay was... it was pretty janky. You'd spend more time debugging your go-codes than actually thinking up a strategy. I'd love to play a modern take with good AI... but what do you know, today's AI broadly speaking in games is just as stupid as it was 20 years ago. Maybe even worse, since at least back then people tried to make AI work in a sandbox, now everything just seems so nauseatingly scripted.
But if you get past having to learn the game, and having to find 4 other like-minded people to play with... there's nothing quite like Siege. Easily 10x as tactical and engaging as any of the older R6 games. Yeah you have to develop some baseline competitive FPS skills c'est la vie.
As for the new GR BR. For one it doesn't really sound like a BR from what I've heard... though hey I love BR so if there's a proper BR mode so much the better... I think they are probably on the right track. BF2042 beta so far seems to be getting a bit of a tepid reception... and I kind of get it... You're in a 64v64 map, the stakes just don't matter. The real hook of BR is getting on with 2-3 friends and going you against the world in a sandbox. Emergent gameplay if you will.
Battlefield has too much running in circles trading capture points, one sided games where if you went 0-100 or 100-0 the end result would still be the same. I can enjoy BF conquest just on the fun of the gameplay a lot of the time. And if I have some friends on we can occasionally actually turn a game around but it tends to be more exhausting than fun when you go try-hard.
So yeah I'm rambling, but I think Ubi is just trying to make the types of games people actually want to play. I'm hoping they do a good job with their upcoming F2P slate. Looking forward to the new Ghost Recon, and maybe the Division... xDefiant is uhhh... ya know I can't say I'm optimistic there. And uhh the R6 Quarantine or Extraction or whatever it's called looks not great but I was never into the Left 4 Dead or COD Zombies horde mode stuff so whatever.
