Been playing this for a bit today and it's not without issues but does end up delivering the medieval classic GTA experience to some degree.
The controls can get quite frustrating and the mini-map is not particularly useful when galloping along, so you end up not knowing where to go, or trapping yourself in a dead end and a swift death by police. NPCs that are following you have poor pathfinding and get stuck so you have to manoeuvre them around objects. Weapon selection seems to reset to bow after dismounting a horse. This is all the PS5 version so others may vary (the mouse and keyboard controls on PC are a very different experience from the demo I played).
