'Probably' everything that ripped off Resident Evil - File 2

Crimson Peak (2015) vs Code: Veronica (2000)

Stories are completely unrelated, but comparisons can't be coincidence.

Lucille and ¹Thomas Sharpe vs Alexia and Alfred Ashford

Lucille is unhealthily obsessed with her brother, just like Alfred is with Alexia.  

What's this?

¹Thomas Ashford

Hmmm.

Welcome to Raccoon City (2021)

Book One
Perhaps by accident, but the first part of four-piece Hong Kong comic series (later translated into English for American audiences), swapped the position of identical twins.

Allerdale Hall vs Private Residence

Sure there's no creepy doll suspended in mid-air, but gothic principle remains.

Book Two
In the game, Steve doesn't explore area with Claire.

Now let's look at more obscure details.

Lucille's ring vs Alexia's choker

Ants eating butterfly vs ants eating dragonfly

And my personal favourite.

Lucille tells Edith (Mia Wasikowska) the music she's playing is an old lullaby she used to sing to Thomas when they were young.

Dialogue makes no sense, as piece is only instrumental.

After Alfred awakes Alexia from cryogenic sleep, Chris (before encountering Wesker), sees lady pants on a monitor screen while searching for Claire at Rockfort Island.

There was a friendly, but naive King, who wed a very nasty Queen.
The King was loved but the Queen was feared.
Til one day, strolling in his court, an arrow pierced the kind King's heart.
He lost his life and his Lady love. 

I don't think beautiful melody and/or tragic lyrics were based on anything.

Bottom Feeder (2007)

A group of people are trapped underground with a scientist mutated into a hybrid creature by his serum.

Dr. Nathaniel Leech vs Dr. William Birkin

Serum vs G-Virus

Creature vs "G"

Unlike Birkin (who gets stronger with every skin he casts off), Leech literally becomes what he eats.

Krendal vs Ada Wong²

Double agents work for very different agencies, to acquire, what do you think...

²Femme fatale was almost a generic lab researcher called Linda.

Charles Deavers and Kenneth J. Sullivan³ both lose their heads.

³Uncensored versions of RE (1996) only, most famously the PC.

Finally.

Dr. Nathaniel Bard was created exclusively for RE 3, which you all know I love. 

Err, surely Capcom didn't lift name?

Death Valley (2021)

Shudder exclusive was directed by Matthew Ninaber and about as blatant as shit can be.

Alpha Team

Gavin

X. Cheng

Rachel

Bravo Team

Beckett

Junior

Moses

Preacher

Olek

Beckett vs Leon

'Likeness' was not lifted from any video game.

In a stunning twist:

Jeremy Ninaber vs Johann Urb - RE: Retribution (2012) 

WHAT?

Cadaver vs Nosferatu

Militia Boy vs Hunk

Infected Man vs Turning around zombie

But the prize goes to:

Monster vs Licker

And (apparently) lifted from RE (2002).

Yeah, not the Gamecube remake.

Climax to follow (at some point in March).
