Remake sold 1,4 million
RE0 sold 1,1
Mikami thought the old mechanics were hurting sales and changed the series with 4
4 sold 1,6 million (only 200,000 more than remake)
Mikami left capcom when they decided to port the game to the ps2
4 sold 2,2 million in the ps2
They changed the style and the sales didn't change a lot
