What we know: the released date was pushed FORWARD.
What we can deduce: the developers must have felt confident that there product was fine and finished
In conclusion, the game was finished but was met with unforeseen problems after release. Just the fact that the release date was pushed forward means that they were confident so don't go saying "OMG THIS IS UNFINISHED!" actually think before you act because you just got SERVED!
A patch (DAY 1 for this game) is for something that is missing. You patch a hole. So, in theory, a patch for a shirt is a coverup for a HOLE in the shirt. Thus being an incomplete shirt.
SERVED!!!
Deduce that they were complacent with what they had created. They might have been finished in thier minds. But it the end....the product isn't working they way they thought....therefore, it's not completed.
