PSGamer: Monsters lurk around each corner, waiting for the most devastating moment to strike. When they do show up, no weapon in your arsenal will stop them. These Monsters are not Escape Dead Island’s zombie antagonists. They are something much worse than the walking dead. These monsters are glitches. A horde of glitches which ruin this unique take on undead survival.
Fatshark CEO Martin Wahlund states that a strict release dates can hinder a game's release if it doesn't allow developers to polish the game.
Well the developers need to be at a set point in development before they can put a garuntee on the date. Its up to them to know if they can get it done and polished in a realistic time frame. IMO, the game should be playable from start to finish before a date is set. Then from there they have time to polish,bug test,and any other sort of fixes before the release date. All we get now are ship now fix later type of mentality.
GameWatcher - Warhammer Vermintide 2 developer Fatshark explains why their last game Escape Dead Island disappointed, and how they learned their lesson for the first Vermintide: "the key thing as a developer is to control your release date".
