RE4 was literally what they wanted to make from day 1.
They started pushing the fixed camera as soon as possible, 3 is literally just an action game. CV gives you so many weapons and ammo you get to the plane with like 600 rounds.
Mikami wanted Re1 to be a shooter and Kamiya has never made another game like 2, and his attitude toward game design clearly reflects he probably didn’t even like making 2. His version of RE4 was Devil May Cry.
Western markets were the ones who actually wanted and liked the old style as well, it’s pretty clear from all their future projects Mikami has always been a tone deaf action man who will shove anything into a game, and Kamiya is not obsessed with spectacle.
The series is unironically in better hands now.
