Resident Evil Requiem's director, Koshi Nakanishi, has made it abundantly clear that the two games which most closely relate to his latest work are Resident Evil 2 and Resident Evil 7, both of which you can buy right now at a sizeable discount via the Fanatical Capcom All-Stars Bundle.
Requiem is a new continuation of the mainline story, meaning you don't need any prior knowledge of Resi to make sense of the unfolding narrative. With a new protagonist, Grace Ashcroft, who will explore places of interest in the Resi universe, including a destroyed Raccoon City. But some prior knowledge will help sniff out easter eggs and get a good grasp of how the story will likely unfold.

To this end, two Resi games will be the most helpful to play. Resident Evil 7 is the first that comes to mind, as this was also directed by Nakanishi and follows a similar structure of introducing a new protagonist who is unfamiliar with combat to the world of Resident Evil.
Then there's Resident Evil 2. Nakanishi has explained how Requiem will fall closer to RE2 as opposed to Resident Evil 4. RE4 is considered to fall on the more action-focused side of the series, while RE2 is thought of as more horror-oriented. Meaning we can expect Requiem to be scary. And a good way of knowing how scary it will be is to simply play RE2 and figure out if it's a level of horror you can stomach.

There are 23 Capcom games in total that you can pick from in the Fanatical bundle, including classics like Resident Evil 2, a Resident Evil 4 and 5 double pack, Resident Evil 3, and Resident Evil 7. Alongside these are other brilliant Capcom games like Ace Attorney, Okami, Onimusha, and Devil May Cry 4.
Buying two games will reduce the price to $6.50/£6.50 per item, three will reduce it to $6.33/£6.33 per item, and four or more will get the games down to $6.25/£6.25 per item, which is the best value for the games.
But just because it's cheaper doesn't mean you have to buy more. Only get the ones you really want, as any discount is still a great price, especially for these classic Resident Evil games. So if you want to brush up on your Resi lore before Requiem, you have two weeks to pick out your games of choice and capitalise on the deal.
