The POI with 14764 zombies "living" in the same house (nerd pole to the roof/loot, done)The AI of engineering college grad zombies
The stamina simulator 2018 (better now)
The "simplification" of guns and parts
The level gating "grindfest" / Changing of learn by doing
The almost "elimination" of mining underground
The "building" is kinda gone
ALL of these (with the exception of the mining underground) can be fixed by tweaking numbers and we should be fine... but... Trying to balance "survival, RPG, FPS, Tower Defense, Voxel building, sandbox" would be too much work or even impossible for a team like Blizzard or Bethesda. For this to work they'd need a team for each genre and listen to each to make sure that any of the other teams plans don't interpose the others.
The lack of direction and the confusion as to "what" the game is going to end up being is whats turning me off at the moment. Is this the next Killing Floor/Dying Light? The next great Minecraft for adults? Fallout 7??
If your answer is ALL of them, we have a problem...
