I bought the game way back at release, but didn't start playing until last month. I have only positive things to say about Torment: Tides of Numenera. It has exceeded my expectations in every way, and I have no doubt that at some point in the future it will be considered a cult classic. I only wish InXile had made more money on this endeavour, as the game is truly amazing and InXile deserves a significant financial reward for making such a unique game.
My biggest fear about this game (and the reason I waited for months after its release before I finally started playing it) was that because it only received 3 post-release patches, the game would be plagued with bugs. But rest assured that Version 1.10 is indeed in great shape! I've read online that some people are still experiencing bugs, but in my 40-hour playthrough as a Nano I didn't notice a single bug.
I'm an OCD completionist who attempts to do all quests in a single playthrough, so games usually take me FOREVER to complete (it took me over 190 hours to complete a single playthrough of both The Witcher 3 and Dragon Age: Inquisition, for example). I'm usually so exhausted by the time I complete an RPG that I usually never touch the game ever again after I finally finish it, haha.
In the case of T:ToN, it's actually a really short game (I completed it in 40 hours, and that's super short for me). The length of the game could be significantly shorter or longer depending on how fast/slow you read the text (you could make the game really short by just clicking buttons to skip all the text, or make the game really long if you have the patience to pore over every detail).
The good thing about this game being short is that I wasn't completely exhausted when I finished it, and I've actually decided to do a second playthrough as a Jack. I'm having just as much fun on my second playthrough as the first, though I'm guilty of just hitting buttons to skip much of the text this time around. I'm guessing that I might be able to finish the game in only 20-something hours this time around by skipping most of the text. There are multiple ways to resolve each quest, and it's been fun to experience the different quest resolutions on my second playthrough.
