• Broken Base: Between DayZ players and ARMA II players. A number of DayZ players find the core game to be a boring, obtuse game that only Armchair Military types would even want to bother playing. Meanwhile, ARMA II players get annoyed by the fact that DayZ and mods like it are going against the core game's strong teamwork-based mechanics and military simulation theme.
    • Many players are angry that, despite being in development for three years, DayZ is still in alpha, with the game still plagued by bugs and hackers with very few features being added to it. Just check the Steam reviews; the reviews users vote as most helpful are all negative, calling out the developers for the drawn out development time.
  • Just Here for Godzilla: DayZ has done this to the original ARMA II that the Steam store page for the basic Arma 2 game has a service warning (usually reserved for serious regional compatibility issues or the like) informing the user that the mod requires the game's expansion pack and providing a link to a suitable discount bundle.
  • Paranoia Fuel: The other survivors. Even if you team up and make friends with someone, there is nothing stopping them from stabbing you in the back later (or you from doing the same for that matter). A writer at The Escapist has even commented that the primary source of tension and horror in DayZ is not the zombies, but the other players.
    • This will often result in the most horrifying noise being not the groan or barking of a zombie, but distant gunshots or the roar of an engine.
    • Humans are the real monsters is the inevitable result.
