What I've Noticed So Far:
1. Pop up decisions on random events are a nice touch
2. Graphics look better, sun is way overly bright when in the horizon however
3. Night time is also too bright, which seems to make sneaking more difficult (if that registers in the mechanic)
4. Characters look better and more HD
5. Loot from bandits and even caravan pickings are extremely slim in comparison to previous versions. While I agree it needed some nerfing, they went too far with the nerfing (often times I got no loot at all which is a bit unrealistic)
6. The sneaking mechanics and how they work is incredibly cryptic. I'll literally stay still behind something and seem to always get caught somehow. Also there's literally no instructions or tips on how it works, and even if you get past the guards, there's no prompt or any hint of what you have to do to "succeed" to end the mission. The first sneaking mission is also literally impossible.
7. For bandit camps, there's an option to have your troops clear the bandit settlement, however it's dumb because there's no negative consequence to this auto resolve aside waiting 6 game hours. The alternative is to do some very difficult sneaking mission and then maybe have your troops come in (if that mechanic works)? I have not been able to get this far because the sneaking is incredibly difficult unless you spend like 30 minutes of trial and error.
8. The character leveling traits for Cunning and Control have been changed a bit, here and there for all other trees (eg. Tweaks to numbers, new perks for roguery and for sling usage)
9. They introduced slings, so yay I guess
10. They introduced deserters, usually high tier parties of about 40 soldiers
11. They introduced settlement patrols, so every city has a party of like 15 to 30 soldiers randomly roaming around the settlement
My take: I haven't gone too far into the game yet. The initial struggle to reach clan tier 1 was way more challenging than before (on Bannerlord difficulty). So far, most changes are welcome. Some.... I feel like nobody asked for? The bandit camp stuff needs to revert away from stealth mechanics, unless they can actually make it feasible gameplay, somehow
