I didn't like this game at first try, started up a new playthrough and about 50 hrs or so in. Am I the only person who has not tamed a horse and sees no reason to? I prefer going around on foot, and paragliding around.
My issues with the horse taming/riding are double-sided:
1) The maximum distance that you are able to call your horse over is not nearly enough. Basically if you get sidetracked a little bit or head up some terrain your horse can't cross you'll quickly be unable to call it forcing you to traverse through other methods again. That could be negated if there were more stables but that leads to;
2) Not nearly enough stables. I get why the stables are placed as they are in the world but the first issue wouldn't be such a problem if there were more stables to pick your horse up.
Those issues basically play into each other to the point that unless you stick to the roads there's no point in taking your horse along. Considering that all of the fun comes from exploration, how long does anyone stick to the roads?
