I can't recall ever hearing anything but that it would be co-op. That was in from the original premises. It's a little hard to shift something that was in there from the start. There's no major shift, you just seem to have some very high expectations, expectations that cannot be done on D:OS budget as it appears.
I don't think any RPG in the last 15 year gave a damn about a balance of realistic or simulation.

Ehm, your calculations are off, there being 6 stats nd all. That makes 4-2. Hey, that's the same as D&D. Unless one points charisma (being pretty) as mental skill, lol!
Unlike D&D however skills and stats aren't linked. And apparently that abhors you. Why? It does allow the player to use their skills more freely since you aren't bound to getting penalties for not raising stats you never wanted to have in the first place. And unlike D&D, you don't need to put points in intelligence to get the most out of skills (since most are linked to said stat). How is that a bad thing? Fits perfectly in a class-less system, but apparently you have an issue with it.

@ Nemesis; There is only so many times you can delay a game before money runs out. And unlike with a publisher, where they can simply ask for more money to add feature X, and get a potential yes, that's not the case for a crowd-funded project. The money is the money, and if it's up, it's up. It's in many cases harsher for developers than a publisher can be.
People think because of Kickstarter, because of no publisher, developers can wait as long as they want to finish their games. People often overlook that this costs a bunch of money, because you need to pay your employees. And thus, no, that's not exactly a freedom they enjoy. They may get some income out of Early Access on Steam, but we all know the majority of income will be once the game is done and sold 'for real'.

Although I have to admit I come from a background playing Baldur's Gate and similar D&D games, and never played the famous Ultima's. Maybe that makes me easy to please, since it's just so much better than modern RPG's, and the few attempts I saw at NPC cycles (The Witcher) were not that good at best.

@ Cromcrom; The game was never intended to please the Majority of players. If so, they never would go old-school, and instead went something modern, with copious amounts of handholding, ego-stroking, and enemies that are so simple even my mother could defeat them since difficulty might make people stop playing. Heck, if they wanted the majority, they shouldn't make RPGs in the first place. Or PC-only.
Then again, Kickstarters like Torment, Project Eternity and Wastelands2 (all around 4 million each) show there's definitely a market for games like these. It would be quite the mistake to addapt the game for the 'majority', the ones who want it to play like Diablo III.

I've seen several hunger/sleep systems, and again, they indeed were very annoying. If 'deep' is the same as 'irritating and obnoxious' then I would agree, depth is missing. But that's what the modding tools are for, and then people who would want to find beds to rest or eat food to survive could install that mod if they want and make their own little 'hardcore game'.

There's a single link in this thread, and it leads to another thread on this forum, so no, no modlinks here.
To 'define' your character are abilities and talents. I'm not quite sure why the epitable of character design and definition is from stats only. There's more than that. Even in D&D stats don't really 'define' a character in the slightest. They were just there to help him or her make the best out of his or her combat abilities, just like here, actually. Of course they bound them to skills, making it a bit more complex (and forced on what skills you could or should take really), but here, they don't make that similar mistake.
Also, how is 'feeling' even a stat. What's it supposed to do? How is perception 'not a proper stat'... what the hell is that even? I don't know.

That this unbalance leads to attributes point spending flaws

What does this even mean? Because you aren't forced to place points in a stat for abilities, this is 'unbalance' or 'broken' Or what? I have no clue.

because attributes and abilities don't share the same pool, is your problem

So, it must be like Drakensang, where you have one XP pool, and stats take 100x the cost of skills, but you use the same points?
While it works (no, not really) for The Dark Eye might not make it perfect for this game. It doesn't even work this way in D&D. And unlike D&D this is a classless system, forcing people upon certain abilities like you want is not the design goal. As soon as you start understanding that, probable the better it gets. This ISN'T D&D.
Everyone can be a sneaky lockpicker, not just a 'thief', everyone can take upon a bow, not just a ranger. Someone might want to combine melee and magic, it's perfectly possible. So, what's the problem. I don't see any, but you do. And somehow it's related to stats, and I'm not seeing it how much I look at it from every angle.

What does 'freedom' even mean. Is every game not open-world like Skyrim suddenly hardcore now. Since linear story development and open-world exploration are 2 completely different ideas where hardcore or casual has nothing to do with in the end. I can agree the lack of questmarkers is "hardcore" (and thank the lords for that, stupid questmarkers), and it's replaced by READING INSTRUCTIONS (super-duper hardcore dude, reading!) The game has some balance issues at the moment, yes (what game doesn't), but to call it 'weird character development' goes a bit beyond me. I would more ascertain that for Oblivion, where staying lvl 1 always was the best, and improving levels were severly punished. I call that weird development. What's weird here?
Yes, it's scary. Having to read again in RPG's. Having to use your brains again in RPG's. Having to thiink again in RPG's. It's sure is scary for many players, but with Kickstarter that seems the way it's going to be... and I LOVE IT. If people dislike reading or using their nogging then RPG's aren't for them in the first place, and I would be glad if they can themselves realise that, instead of developers making RPG's so extremely lite and a betrayal of themselves to suit to players who don't even like RPG's.
The only one really repulsed so far is you. On Steam I can see some people being confused ("I was expecting Diablo!") but that's not really an error with the game itself. Aside from that it's mostly bugrelated questions and concerns which can cause confusion. Confusion, not repulsion. But feel free to point me at one SINGLE other person who seem 'repulsed' like you.
