My first run through was about 20 hours, and I missed a few quests. Also, there are two VERY different paths through the bulk of the game as well as enough NPCs that you can make two full parties. Personally I think I'll get 3 or 4 runs in the game without problem, so that adds a lot to the overall value.

That said, this is not a super long game like Pillars of Eternity, but I quite enjoyed my first run and am enjoying my second even more! I don't normally buy games at release or for full price, but in this case I did to support the developers and I think I am getting reasonable value. That said, wait for a sale if you have any doubts at all!

There is not much of replayability to be honest.The second part felt far to much unfinished to play that game again.The writing is far to predictable if you have a lot of fantasy books and games behind your back.I was predicting the unbroken quest line since the moment i talked with the armored companion.I doubt that there will be something amazing after rereading the first 10 hours of the game.If there was an option of starting the game after the first act ....maybe.The whole blocking areas of the game is moronic decision.The game is very short as whole let alone after you gate half the content.If you skip all the writing you can finish the game in a few hours.To me that game is not worth any money.The reasoning for me is that it leaves bad taste in my mouth(The one of disappointment and frustration).I am a huge fen of Obsidian and have all of their RPGs,they may be buggy but for me they are one of the best rpgs.Tthis game feels like BG2 finishing after you complete 3 side quests and then you give the money to the respected side.Then Bodhi or Aran Linvail tells you what is happening after that.

I was with you till you mentioned AoD as the high point of replayability. I am not even going to comment that because I can't say anything without sounding like a complete ass to you, and I have nothing against you.

Anyway, to each his/her own.

You can even absolutely hate AoD as a game, but the fact still stands that content is different for different characters. AoD is an indie game and has many flaws, obviously, but I liked the story, and for me the story is more important than other factors in RPGs. As for another example of different content on different playthoughs there's always the witcher 2, but I thought comparing mostly text based Tyranny is more fair to AoD than to the Witcher 2, which is what they call AAA.

20 hours of gaming for one way of playing the game is fine with me. At least when we are talking about story based games. As is Tyranny. Considering you can play it at least one different way, that's a minimum of about 40 hours.
For a linear RPG that's ok with me.

AoD is very different for each character, but if you take away the absurd way of handling things (only certain ways can even allow you to play the game beyond a point, if you miss side missions you are screwed, etc) I really really don't see how it can even reach Tyranny.

If I want to play 100s of hours of a game, if not 1000s, I have strategy games for that. But, to each his/her own.

Wow, I have no idea how that could happen. I think I had 10 hours in act 1 alone. Now at ~28 hours I started Act 3. I guess you have to do nothing but the main questline and ignore everything else to make it in 12 hours.

Slightly above 17 hours for me. I was reading nearly all the dialogs albeit fairly quickly and doing all quests I could find.
So, is it worth it? Well, I've already uninstalled it, so... I also get a feeling that it's a very rushed game and not really worth the current price.

Keep in mind the game is not 'fnished' so to speak. As somebody over at Steam has mentioned that at the moment the game has 3 acts and ends abruptly, and poorly. The artbook shows act 4 and 5 stuff, which could instantly spell out that this will no doubt have 1 or 2 future DLC to properly end the game.

Sorry, but such approach is unacceptable. DLC should be only for extra and optional content, not to fix half finished and rushed release. If I knew that was the case I would never have bought it.

Honestly, what I've been reading is a mixed bag... and I mean polar opposite opinions of the 'ending'. Here is one spoilerless example:

So, I guess the best thing is to play through yourself and find out.

It wasn't that long ago when new games had 10-20 hours' worth of content max, if we were lucky. COD 4, while being an fps game, has 4 hours in the single player campaign.

Mass Effect 1, which is heralded by many as a really good RPG, I finished in 18 hours, and that was doing as much extra stuff as I could.

~20+ hours of content if you read the text (I just finished the first map after the prologue and I'm at 4 1/2 hours, and that's not even doing all the content - and no, that's not act 1, that's just the first map) is definitely worth $45 for me. Granted, I got this game as an early Christmas gift, so my expectations aren't as high as someone who paid with their own money... but still, I think some people forget that not that long ago we had many many games with not very much content to them.

If you expect every game to be the length of POE, you are in for heart ache, but really, if you don't think 20-30+ hours' worth of content is worth $45 then just wait for a sale. A lot of us feel it is, though, especially considering it's Obsidian we're talking about, and not some upstart indie dev.

Ok, the game is incredibly linear, but if you relax and play without running and read most, if not all, the dialogue option, it would be easily over 30 hours.

My first blind run took 36 hours and a friend is over 40 already.

OK, great...;) I'll definitely look into it some more...! Thanks much for the comments, guys!

I have put 51 hours into the game so far over three characters, two of them I had pretty much just taken the first spire perhaps a little further but I have by far put the most time into my caster and I have just cleared The Blade Grave.

If you are finishing in less than 20 hours you are not doing side quests, reading through the text properly and most certainly avoiding killing everything in an area, I can only think you have a photographic memory, the whole point of an RPG is to read everything talk to everyone learn as much as you can about the world and feel part of it, its not Sonic the Hedgehog run through the level as quick as possible, I wonder how many people are using guides and not figuring things out for their selves.

I'm half expecting someone to come along and say they finished the game in under 20 hours on Trial of Iron settings and didn't have a party wipe.

Unlike PoE Tyranny keeps me interested, I got half way through PoE an got very bored, the story and lore are far me interesting for me in Tyranny, PoE felt like so many other games I had played before, I know it was kind of paying homage to BG I get that and I wanted to like it but it was a struggle to play.
