tl;dr Left a negative review around 1.4.x? with 70 or so hours and am closer to 300 now and still negative, just update it. Game is a solid 6/10 - good base to build off of but frustratingly soulless in areas that matter.
Now for the rant...
Devils advocate: Bannerlord is am ambitious jack-of-all-trades (at least that is how it was positioned) that was supposed to hit all the marks for combat, roleplaying, immersion, politics, fief/kingdom management since that is what Warband had (which was deeply flawed on its own) but since it's next-gen you'd expect all of those systems to be built out. I get that's hard to do during a brutal economic crisis manufactured by a bad response to what turned out to be just another coronavirus - add to the fact that Turkey has its own geopolitical and economic issues with currency solvency and fighting a ton of proxy wars in Syria, Iraqi Kurdistan, etc. - it's hard to employ folks with the skills AND theyre doing 4 or 5 console ports all in house...that's a lot to overcome.
While I am sympathetic to all of that, having been a product manager and a principal engineer for larger scaled projects in different settings (outside of gaming), it's still frustrating when elements are missing, bugs are never fixed, and the "core" features such as combat AI, strategic AI and diplomacy are not that great.
Battles are nice, graphics are good, it's always fun smashing guys over the head with 2-handers but it gets tiresome when it's the same ole watching my HAs run into the enemy infantry, my cataphracts having 10% accuracy on thrusts, and the enemy forming up in a donut but I cannot flank them because they magically know where everyone is despite not having Line-of-Site
It's frustrating when I need to cheese policies just to stop fiefs from collapsing all the while my AI lords have zero respect for me as a ruler, even if they were a former companion, and I have to constantly resist their desire for war. While campaign/Army AI has improved a bit to be more cohesive, that model breaks immediately there is a 2-front war or if there are defensive and offensive actions required. Party targeting behavior is still really bad.
The economy is manic at best, with workshops and caravans having no real rhyme or reason why they earn money or not, any economic warfare is null since enemies spawn with gold and troops and don't have a concept of running into bankruptcy which is what mostly ended wars to begin with if there wasn't an outright massacre (which there really wasn't since 60% of the world died - there were not 60K doom stacks running around). While I can build out towns and castles, it's all rather static and the scaling for construction is very poor and still doesn't give great bonuses. Doesn't matter if I have level 3 walls the auto-calc will still decide.
Late game is also dreadful. With the lack of roleplaying and the fact you cannot do many quests to begin with and are too busy micro-managing the stupid AI and dealing with raids...it becomes a chore...like the end of an EU4 campaign and burns me out.
And that is all to say that I still like it - early game is almost always fun, smashing dudes over the head is always fun, coming in clutch to save a party getting gang-stomped or to lift a siege, unlocking weapon parts or getting good drops is awesome as is winning close-quarters combat against the AI to get a victory during a siege or killing an enemy lord. There are legitimate parts that are exciting but once you do it 5 times it's a grind again.
And I am not even sure mods can really fix that gameplay loop.
