again, 2 was already complete as it is. most of the cut content of 2 was from the 1.5 version. 3 was made separately after 2 was released.if campcon had any artistic integrity left they should have made 2-3 as a single game they way it should have been.
after 2, capcom was trying to mix up biohazard because they dont know where to go after city wide infection, which resulted to making a game based on feudal japan times, dubbing the project as sengoku biohazard, which turned to Onimusha, which got delayed so much that it moved to PS2 and scrapping the PS1 edition
(some surviving screenshot of the PS1 edition of Onimusha)
then the proposed Saturn port of RE2 was not going well, which transformed to Code Veronica project for Dreamcast. and the Leon game which he explore the Spencer castle turned into Devil May Cry
3 was made as Capcom was panicking that they dont have a game for 1999. so the game was rushed out the door, but still, Capcom made an awesome RE3 game as it is. I find it more enjoyable to replay than 2
