Single player is also pretty good as an opportunity to test things out without paying the penalty of losing your equipment if you do something wrong.
I tried it and was a bit freaked out because it has that "saved time" countdown which makes me wonder if it is updating the central server with progress in single player, if so then I think that may be a risk of being seen as a hacker since Rocket the dev responsible for DayZ has said he doesn't want a SP version... and he has perma-banned the people who were guns/ammo hacking the earlier versions of DayZ.
So for me I will probably pass on playing further single player sessions to avoid the risk of being banned since I really like DayZ and it would suck to be banned.
