RE4 isn't resident evil. it's a generic 3rd person shooter with a loose attempt to tie it into RE by using leon and ada. no raccoon city, none of the familiar zombie types except generic zombies, not even any interesting zombies because they all acted and looked similar (le slow boring guy who has a shield, guy who is slow and regenerates, slow guy with a crossbow, etc), shit story, gay quicktime events, vendors, atmosphere that didn't give the player the impression of being confined and claustrophobic that made it urgent, savepoints everywhere, bosses you could just kill with bought rocket launchers or with ones you found lying around.
the original RE games were survival horror games first with puzzle elements and the atmosphere and confinement plus the controls and camera and well-made game design crafted around survival and slow progress made the series what it was. RE4 was garbage as a resident evil game because it put le shooter game first and then designed around it and catered to casuals. only good as a generic 3rd person shooter. truly a shit "resident evil" game. imagine thinking RE4 was good lmao
