That might make more sense if basic mechanics and the story were the sum of what makes a game. I'm pretty sure there are other things that influnce people though like the soundtrack, atmosphere, the setting, etc.
No one without brain damage would say those things are the same in both games dude, I'm not even sure what we're debating anymore. When I say Witcher 3 and AC: Origins are the same game, I am obviously not saying Witcher 3 is set in Egypt and stars a black dude avenging his dead son. How is it not incredibly implicit in my remarks that I'm referring to gameplay and general game structure/genre? The little poke I made with a smug emoji was at people who rant on here about "Ubishit" and "mainstream quest marker faggots" who then vote Witcher 3 the 15th best game of all time. Those people are storyfags to the max and massive hypocrites who I like to tease. Simple as that. You're reading too far into it.
