I fecking love this game.
I get the complaints about clunky controls, definitely could be smoother. Doesn't bother me too much, though, and I imagine we'll see some improvements after some patching.
The complaints about pace I do not get. This game is meant to be ridiculously immersive, and I love the fact that you seem to get into trouble if you run around, bump into people, etc. It makes sense for it to be so slow in the beginning in the snow, as anybody who's maneuvered in deep snow can testify to. The speed of movement, the need to spend time bonding with the horse and maintaining your equipment, as well as the penalties tied to clothing, fatigue, nutrition, etc. help make things that much more immersive, and makes you feel like you are in a world rather than in some sped-up fake representation.
Games like these always make me want to take my time anyway. I love riding around, observing my surroundings, taking things at a natural pace. I get that for some people that's not what they want, but there's no way of pleasing both those who want to get lost and immersed and those who want a quick video game romp.
I looove the social mechanics of the game, too. Like that lippy guy mouthing off about the O'Driscolls in Valentine, I was ready to just move on past him, but he kept pushing my buttons and I squared up to him, and then all of a sudden I'd bloodied my hands and incurred a bounty, all because the game managed to poke at my sense of pride. The way that situation unfolded and escalated was really life-like, and I find myself not knowing whether I'm about to get into hot water or not when I interact with people beyond pleasantries at a distance.
