I'll tell you how my character usually died. The first time was on a fishing quest, when the fishing rod was not displayed at all, which is why I could not find it. While I was wandering around looking for it, a warning flashed on my screen for a split second that I was leaving the quest area, and the character instantly died. The second time my character died was in a quest where I had to keep an eye on a villager. She went too far away while I was dealing with the inquisitors that had spawned for the second time. Because of that, I saw the warning blink on the screen for a split second again, and my character died. Another time the character died was about 50 times when I loaded from the last save and appeared at a fire pit that was outside the quest area, causing the character to instantly die after a half-second warning. Since the older saves were VERY old, I struggled with the buggy save. Until the warning worked as it should, not for a split second, but with a relatively normal decreasing progress bar, and until this bar reached zero, I, like a fucking speedrunner, tried to run back into the quest area, which I managed on the third try.
I haven't played the UE4 version, so I can't say how playable it is. But I can definitely say that the UE5 version is broken down and across, balancing on the edge of unplayability. Instant deaths, quests that break after loading, NPCs that disappear after loading, teleportation under the map/water every second time you mount a horse. This game is VERY far from the AAA level stated on the developers' website. Even considering all the rawness and poor quality of modern AAA.
Despite all the shortcomings, the game is visually cool and the gameplay is somewhat addictive. That's why I'll wait for the developers to finish it. I think in 5-10 years, they'll make a finished product out of it. Of course, if they don't break the game every time, porting it to every new shiny version of UE.
