For the first part of the question it is these two.....
These two use to be apart of my top three favorite developers, but by the end of this past gen I pretty much stop caring about much of their current and future. FromSoftware in particular I figured they weren't really for me anymore a bit earlier than Blizzard in during the gen. Main reason why for FromSoftware is because I was a fan of their mecha titles, mainly Armored Core but I did enjoy the others like A.C.E. series, Chromehounds, and Gundam Unicorn. Mecha game were pretty much my favorite "type" of game but they stopped producing them after the success of the Souls series....which obvious worked incredible well for them and even though there is suppose to be a new Armored Core in development I just don't think they'll produce as much as the same titles that I use to love as I'm not a fan of their current output.
In Blizzard's case it's more that I've grown out of what they make. I love Starcraft 2 like I played that shit for several years and I played Overwatch for a while when it came out but after a year I dropped it and started not to care about what Blizzard was producing. Stuff like Overwatch 2 and Diablo 4 have about zero interest to me right now. Most important thing to mention is Blizzard's bullshit when they banned Blitzchung because of their mention of the Hong Kong protest. I think that was the point when I was done with them.
As for a developer that I became a fan of.....
I liked a lot of the first Dishonored but 2 and Outsiders(which I played recently) set the bar a lot higher. What really got me though was Prey. I didn't a lot of expectation for it as before playing I've heard it was like System Shock and I never had played that game before, but once I p0layed Prey I was hooked. The atmosphere, cool ass abilities and exploration I just loved all of it. One of my favorites from this past gen absolute and their next game Deathloop looks to be another banger as well.
