You read that right, a decent portion of the main story will be fully voiced, the first two chapters for the demo are already voiced, and if things remain as they are, the rest of the game will be too.
I have been quiet but the game is being polished up a lot compared to the current videos out.
Additionally while still in its early stages, the game will feature music by one of the best musicians around, once everything is finalized I will openly announce who it is.
