If you want to make any kind of adventure game - 2D, 3D, 2.5D, with any sort of control scheme or dialog system you like, then you need this plugin. I was super impressed by the breadth of features it supports, it's what I've been waiting for: a specialized tool for Unity so I don't have to reinvent the wheel but can make the games that I want to make.
Chris is a gentleman and a scholar and has all the chops needed to understand which features to implement after years of working on adventure games himself. He is quick with support and tirelessly improving this thing all the time. So jump on board, this train is only going forward!
