RyaReisender: Shallow - After you learned everything, yes I guess. It's not shallow the first 10 hours you play it, though. I guess the DLC increases that time to around 12 hours.
As somebody who has been involved in Steams EA for the duration of development... 10 hours? Really?
I was still learning things after 100 hours post-release, even with all the information gained during development. Going by the forums, 100 hours was estimated to be around the time where everything starts to click together in terms of player knowledge.
Considering that you won't even get best equipment for at LEAST 30 hours of play time (or brothers skilled enough to use it), I dare say you are severely underrepresenting the entertainment value of the game.
RyaReisender: Repetitive - It was super repetitive, doing the same 5 things in endless loop. With the DLC it changes to doing the same 6 things in endless loop. So it's 20% cooler I guess.
It is about as repetitive as Jagged Alliance 2. Considering that enemy types are somewhat tied to game progression, and things like end-game conflicts do not occur early on, I guess the game rubbed you some wrong way to make such duplicitous statement as yours.
RyaReisender: Unfair RNG - That's part of the design and intended. Like Darkest Dungeon or Battle for Wesnoth.
Ironically, the RNG is very much fair in its randomness. Some enemies might be considered "unfair" (don't fight goblins during the day!), but in general indeed, it is not a game that hand-holds.
RyaReisender: Bad AI - The patch notes indicate that the AI was improved. Giving it the benefit of doubt.
What was the problem with AI in the first place? I can think of only a handful of situations where AI did not react to really cheesy tactics (relying on knowledge of enemy reactions in the first place, and conditions that negate them). For that matter, I know a lot of people failed to appreciate that the developers specifically wrote enemy behavior to match their archetype. Weidergangers don't hold formations. Wolves will just swarm you. It's only the "intelligent" enemies that will show more complex behavior, and even then there are some "species" preferences (greenskins will still WAAAAGH!)
RyaReisender: Bugs - Didn't notice many bugs even before this DLC. I think all the critical bugs had been fixed long time ago.
Haven't run into any since about the second post-release patch, but as usual YMMV. Don't think I've seen anybody reporting any major issues for a while, either.
Battle Brothers is a fantastic game. Not for everyone, but if you enjoy RPG tactical combat (with a side dish of management), it's one of the top titles in my opinion.
