Interesting question/good thread. Many awesome Games-Studios, its really hard to say..
Naughty Dog are the Best for me = ) And then..
Guerrilla Games, Santa Monica and Insomniac Games are strong,
Media molecules are very creative. "Dreams" is the most innovative game in the world in my opinion, EVERYTHING is possible.
The Japan Studio is interesting.
Sucker Punch is working on the biggest game in its history: Ghost of Tsushima. Cant wait of July!!
I am very excited to see the result of the survey.
