I don't care much for online reviews. Otherwise I would've probably cancelled my TLOU2 pre-order because so many people hated it. Now I'm really happy I didn't because I absolutely loved the game. The story is way more harsh, realistic and less clear on who's "good" or "bad" with new characters so now I understand why people who expected part 2 to be the orginal game but some years later were really disappointed, but I loved it.
Back on topic: the same here, some people are going to hate it, because they hate it or even to get more clicks/likes which requires to stand out, so hating a loved game might just do that. I'm going to play it and I'll make up my own mind
I love the horse riding stuff. If I could get it with a GTA style ingame selection of radio station, I'd be playing just that all day long.
It's only the colors and names that are different I think, not like deciding between Ferrari, Lambo and Porsche.
I read on a IGN page with "tips and tricks" the horses are all the same, so pick whichever you like.
