I think they definitely took a risk with the way they crafted this game. I think there will be plenty of people who see a Rockstar game and assume it will be like GTA: fast paced, zany, shoot first ask questions later.
But what you have here is a very grounded, VERY realistic game. I love it personally, but I get why others may not.
My favorite thing so far is riding between point A to point B. There's always something interesting to see as you're riding along. RDR's random encounters were all scripted, but in RDR2, it just feels like the world is alive and things are happening, whether you're there to see it or not. It doesn't feel crafted just for you, which is an immense achievement in an open world game, IMO.
An example is one I just came across. I was riding down the road, and heard some shots ringing out through the woods (by the way, gunshots sound AMAZING echoing up in the mountains, or in the woods). There was no dot on my map telling me I should go there, but I wanted to go check it out.
I snuck up behind 3 guys, shooting bottles on a log, target practice. They were making comments like "We'll make you a real killer!" it was 2 guys teaching another how to shoot. I just got a bad vibe from them. I called out to them, and they were immediately hostile, threatening me to go away. I tried to diffuse but they threatened me again. So, I obliged and walked back the way I came. They watched me for a while and then when I was out of sight they bragged about how they scared me off. I was hiding behind a tree watching them, and after a few more shots they got on their horses and one of them said "Alright, let's go raise a little hell!"
Before they left, I walked towards them again and called out to them again. This time, they immediately drew their guns. I went into Dead Eye and smoked them all.
Coming away from that interaction, I was thinking about how I could have either not gone to investigate those gunshots at all in the first place, because the game never told me to go there. Or I could have just left when they threatened me the first time, and they would have been free to go do whatever it was they were planning to do.
It's a pretty remarkable thing, I can't remember ever having an encounter like that before in any video game.
Edit: Wow, I didn't realize how long this post was, lol. I could literally write a novel right now about all the things I love about this game
