The fighting, questing and character management of this game is simply dated, hostile, bugged and unfun. Some of it I assume is due to the use of rogue trader pen and paper rules (I don't know to what extent they were adapted, but clearly not enough, or not well enough). An on top of this poor animations, strange fade to black, choppy user experience, and the result is a struggle to get from next story development to the next. I cannot commend the lore accurate 3D modelling, because of its low quality and cartoonish style. It feels strangely gaudy and blurry, while also frying my 7800XTX, somehow. You don't have to apply raytracing, have hyper-realistic models and a enormous budget to look good. Just proper art direction. The first two generations of Dawn of War are a good example of combining a clean, cohesive, pleasing W40K 3D environment and models. Bugs are forgivable, though some will lock you out of important quests and force you to reload. (I lost 4hours, my bad for not noticing I was soft-locked). The roleplay and storytelling aspect is thankfully satisfactory and this game's only redeeming quality. W40K is known for its plethora of sloppy to trashy games, and I assume GW is a factor that tendency. But also, knowing the studio, I was kinda expecting this very dubious result.
Lots of "oh no, the game drove me into an impasse, time to load a save from 5 hours ago", lots of "score a twenty or never hit anyone in this fight", lots of "*confuses whole party from 100 meters away*". And I'm no even playing in harder difficulties. This game has a lot more features than other comparable games, but darn is it unpolished, unfriendly and unbalanced. Oh and the voice acting is sometimes ridiculous (props to that GI Joe angel).
