Above all, Kentucky Route Zero is an argument that games can be more. That argument isn’t nearly so revolutionary now as it was in 2011 when development began, or 2013 when the first act released. We’ve (thankfully) made some decent progress in the years since. People bought Kentucky Route Zero, and those people did go start their proverbial bands.
The Witness has taken hold of my brain, both waking and sleeping. If I'm awake, I'm playing. If I'm not playing (for whatever reason) I'm inking possible solutions into a pad of graph paper. Writing this review I've solved two more puzzles and I think have a lead on a third. It's compulsive. When I'm done and this is all filed away, I'll go right back to playing.
Day of the Tentacle is a classic, but not in the old musty way where you brush off a copy of some old SNES game and realize it isn’t as good as you remember. This is still one of the finest point-and-clicks ever made, with a witty story and some brain-bending puzzles. Also, a hell of a lot of dumb puns.
Thimbleweed Park is excellent, both as tongue-in-cheek homage and in its own right. It's a LucasArts adventure game the way you remember them being, with the same witty humor and, yes, the same sometimes-asinine puzzles. The good and the bad. And really, I don't think fans would want it any other way.
