>resident evil also does this shit.
No it doesn't though?
>Resident Evil 1
Accidental leak of a volatile virus- the leak actually RUINED the product.
>Resident Evil 2/3/Outbreak
Again, accidental. It was a big corporate war over securing samples of a product that went really bad really fast.
>Code Veronica
The product was used as it was designed- by quickly wiping out all living humans in an isolated area before sending in a super soldier or BOW unit commander (this time Wesker, who fulfills both roles) to go accomplish the goal.
>Survivor
Intentional leak by someone who wanted to decimate Sheena Island before he would be arrested and executed.
>Zero
Intentional leak to get revenge on Umbrella.
>Dead Aim
Accidental leak during a three way war between the US Government, the Chinese government, and Umbrella.
>Resident Evil 4
Everything went exactly as intended here. The plaga was implanted in hosts, who were then controlled by the dominant plaga.
>Resident Evil 5
Wesker is not trying to sell anything, he literally wants to end the world to see how far he can push human evolution.

And so on and so on.
The products these viruses sell are not conducive to actual games. You can see the end goal of them in the film Resident Evil: Damnation, where an entire Eastern European war in not-Ukraine is fought using BOWs.
