I'm no Unity expert and have been using alternative point 'n' click software to develop our game. To be fair, it was doing a decent enough job but when I heard about Adventure Creator I just KNEW that this was the way forward.
I took the plunge and haven't regretted it one bit. This asset is so easy to use, even with no prior Unity knowledge (although naturally it helps to know the basics).
If you want to challenge TellTale Games and make a game like The Walking Dead, then look no further.
I can't rate this high enough!
