*As of Book 3* The story is great and the puzzles are fine for the most part. The performance on most PCs is dismal. Reportedly this has been improved with the upgrade to the Unity 5 engine, which is currently in beta. I wish I could say more about the performance upgrade, but RTG has made the beta available only to users of a certain vapour-based platform. New books and patches are also released on the other platform first. Book 3 was released on a Thursday with a bug for some people (altered in-game choices). On Friday RTG released a hotfix. The other platform updated their version of the game immediately. GoG updated on Monday. Since distribution is part of the experience, I include it in the review. Same price, different experience. Will avoid GoG in the future. Story: ***** Gameplay: **** Graphics: *** Performance: ** GoG Distro: *
