Your reason for it not being counted as the same console is that it would be "unfair" and give an advantage to the Switch compared to the PS4. Hence your reasoning is motivated by competition and wanting the ps4 to win rather than logic.
My reason was just "unfair"? I came here and posted "it's unfair" and nothing else?
Can you read again my posts and talk to me again later? Thank you.
