Do you think this is going to be finished before the new year?

Beta chapters are going out to backers currently, but more than likely the full game will not be released before then, no.

Alright, just curious.

So far I'm liking the story line from what I read from the summary and gameplay, really love the visuals and ccgs. I like the soundtrack and the main character already.
