(minor spoilers ahead, if you consider the amount of quests etc. as spoilers)
Overall, I liked Torment: Tides of Numenera, but it is far from perfect. It feels like some of the elements are there just because they "have to" be there. Much like in the original PS:T, there are some features you will never use, some that are horribly underutilized (for example the Labyrinth and its sidequests), and some that seem out of place (I still have no idea what use the Meres actually are, apart from a choose-your-own-adventure type of minigame). Unlike some, I found the battle system to be adequate, and it did not spoil my enjoyment of the game and its story - then again, I had only a half a dozen Crises in my playthrough.
Some have complained about the length of the game, and I have to add this to my list of negatives as well: having completed all the (side) quests I could find and reading all the text that popped up on my screen (I am a relatively fast reader), I took me around 25 hours to complete the game. Maybe the problem is with pacing: with just two major hub areas and a few smaller maps to explore the third act of the game arrives way too fast. There is also both the sense of catering to every type of player (much like in Wasteland 2, you can solve everything in a plethora of ways) and at the same time requiring you to just pump every point to intelligence in order to easily "win" every conversation. You really cannot fail in this game which is both a good and a bad thing.
After finishing T:TON I was left with mixed feelings. The game *is* good, but it just does not quite connect and gel together the way it should: some elements of it should probably have been removed, and some elements of it expanded exponentially. It falls somewhere between okay and good, never reaching its full potential apart from the sold first third of the game in Sagus Cliffs. Worth buying? Yes, but not at the full price.
