Uhh OP your poll asks a different question to your first post. I think the question in the post is interesting, but unfortunately most people are only responding to the poll.
And a lot of those posters are arguing against themselves. "Game reviews should be objective... so reviewers SHOULDN'T consider how outside influences might have impacted their perception of the game" 🤦♂️ This answer misses the point the OP laid out. The current situation could make some reviewers enjoy the game less (seems doubtful to me but that's the premise of the thread). For the reviews to be as objective as possible, the reviewer would need to consider that impact to attempt to remove the influence it has on their feelings toward the game.
To state it more clearly: this situation might make reviewers enjoy the game less if it hits too close to home. To be as objective as possible, should they therefore adjust their scores upwards to account for this outside influence, and attempt to get the "objective" "true" scoring for the game (whatever that means).
For my own answer... The premise itself feels a little far fetched to me. I can't really imagine someone emotionally linking this game with the current pandemic. But, if we imagine that happening, then I guess... No, they shouldn't adjust the score/review. I think the strive to be "objective" is flawed in itself, and a review can only be useful if it accurately represents a person's experience with the game.
