And "Nintendo's mistakes, starting back as far as 1988, were the catalyst for Playstation's emergence and eventual domination." as open as it is, implies that Nintendo have been making mistakes and fuck ups as far as 30 years continuously.
I said "were the catalyst" which denotes occurrence in the past. You're trying to twist what I said into "have been making mistakes" which denotes past and present time, which isn't what I said at all. You're choosing to define what I said as "30 years of fuck ups" to fit your "Sony doesn't get enough cred" narrative.
