I think a single player tutorial is a great idea, and could add to the ambience of the mod rather than subtract from it: Imagine controlling a guy in a pre-outbreak world, where you are doing everyday mundane stuff, like packing a bag before going to work (inventory management), driving a car to work (vehicle control), chopping wood (showing the inventory-right-click mechanism), eating a can of beans for lunch, shooting a wild boar that shows up, etc. The ambience could come from radio news broadcasts that talk about "worldwide rioting". The whole tutorial could end by you trying to outrun some zombies that shows up. When I started playing ARMA II some six months back, I thought the controls were pretty clunky. I've gotten used to it by now, and think the controls are fine now, but I think new players who bought ARMA for this mod should be cushioned more into the control scheme, to avoid frustration that definetly will subtract from the survival experience. Especially after the removal of side/global chat, as it is now impossible to ask more experienced players for help. Furthermore, some controls are DayZ-specific, such as going to the inventory and right clicking to use stuff. In summary: A tutorial is a great idea and could add to the ambience of this mod.
