AiCola: Funny how you can judge the game despite not ever playing it.
Here are the facts that correspond to your claims:

1. graphics, system requirements etc.

The graphics of this game are VERY good.
the 2D Background is done very well and with a ton of love for detail, if you zoom in all the way the textures become a little bit blurry but are still quite nice.
Honestly what would you change with the graphics?
Usually with games like this the background oftne looks very nice but the characters are ugly in comparison (for example shadowrun returns, or wasteland 2, where everything is rather ugly)
In this game the characters look very good, almost like they were hand-drawn aswell, which is quite impressive.
Saying the graphics are bad and outdated can only mean that you simply don't like the isometric view, in which case it is nonsensical of you to comment on the graphics.
please show me a single rpg game with isometric view that has better graphics.

"This wouldn't be so bad if the game's system requirements reflected the fact that this game looks like it was made many years ago, but it has higher system requirements, and costs more than games that are far more advanced. Why? Lazy programming? Lack of programmers? "

Can you give examples of similar games that are more advanced and cost less?
the recent divinity: original sin costs exactly the same, wasteland 2 cost even more i think and was not done as well in terms of graphics.
Which of these games have lower system requirements?
You won't find many, trust me.
I have only played a few hours today (obviously ...) but the game already has tons of dialogue and hand-crafted content.
This type of content costs time and money, don't you get that?
Of course you can "cheat" and make a giant game like draon age: inquisition by just making a ton of empty areas with randomly generated respawning enemies, but that is for people who don't care for story and characters and only want to collect things for copy pasted quest givers that have nothing interesting to say.
None of that bullshit is in pillars of eternity.

" I understand that it is a Kickstarter game with limited funding and resources, but that doesn't change the fact that the game is dated, has high system requirements"

The game first of all is not dated at all, like i said before.
And the system requirements are quite low compared to what is standard technology today.
Compared to the old infinity engine games the system requirements have gone up due to much more complex math in the combat systems and actual real time instead of turn based real time and of course because of much better graphics.
The characters are animated quite nicely, as i said before, and the resolution of all the background textures is rather high aswell.
The game looks AWESOME!
If you honestly think the system requirements are very high then you are playing on a potato and are not able to play any new games at all, what current game are you able to play that has lower system requirements, but looks less "dated"????

2. bugs

i have not encountered a single bug.
Only one very minor thing that i am not sure about wether it is a bug or not, that does not effect me playing the game at all.
When i played wasteland 2 on release it was much more bugged and i even had to start a new game due to that.
Same goes with games like Dragon Age: Inquisition, THAT game was buggy when it was released.
Pillars of Eternity came out today, nobody has complained about bugs and yet you claim that it is extremly buggy.
Stop making up things that are not true please.

3. prize

Like i said before, this game is very huge, probably bigger than baldur's gate, and baldur's gate was not really any cheaper back when it came out.
Your question on how much people would be willing to pay if it was not linked to baldur's gate makes no sense.
The game was funded and demanded by people to be the spiritual successor to baldur's gate.
It is like asking wether people would buy draon age:Inquisition if it was not based on the really great draon age:origins.
If it was not, then it would be a completly different game....
If you look at divinity: original sin you can see that people spend EXACTLY the same amount of money on a game that has nothing to do with baldur's gate, but is made in the same way ...

AiCola: graphics and gameplay:
I know very well that one can inform themselves on the internet and see gameplay footage and what not.
But i also know that almost every time the game will be different from what you thought it would be and you ALWAYS have to play the game for yourself to truely judge it.
I have watched several review by German journalists (for example gamestar and pc games) and they all praised the game and said it has great graphics, yet pointing out that you need to read a lot of things and have to like the isometric view in order to truely appreciate the game.
I also watched some videos of backers, nobody ever complained about the graphics, all really loved what they got.
I simply can't see where all these negative review that you were refferencing are.
Like i said in my last post it would really help if you told us what exactly you think is bad about the graphics.
What would you improve?
Surely you should be able to name a few things.

bugs:
The game was out for less than 12 hours and on this forum are almost no threads about bugs.
As you can see the game runs quite well and is not a buggy mess at all (like wasteland 2 for exampe)
As i also pointed out before other games, even AAA games, are often very buggy on realease, it can happen to you with either game, not just kickstarter.

prize:
AAA games like dragon age inquisition are currently 60€ von Origin.
The first DLC costs 15€.

As you can see pillars of eternity less than AAA games.
Similar games like divinity: original sin cost the same.
That probably means that these games indeed DO cost a lot of money to create.
That is not surprising if you consider how much hand-crafted stuff is in there.
Only because it is isometric doe snot mean it has less content than Dragon Age, Skyrim or whatever other game.

Nowakus: I am all for DRM-free games, but the price difference for this game is just too big. A Steam key costs $20 in China (as I heard), $23 in Brazil (if you are committed enough to set up a VPN for Brazilian IP), and $30 in regular online key shops. So for $30 I have the game already downloaded.
This situation is no good. Does a game need to be 'old' to be worth buying from GOG?

WebJunkie: So what is the difference between the Hero edition, Champion edition and the Royal edition? All the included goodies are FREE as per the statement on the games description for each version so you can't be made to pay for those as they are included FREE!

So what do you get extra in the Champion/Royal edition over the Hero edition of the game? Does each one have more content or DLC than the previous edition to justify the price as all the extras are included FREE?

Alyosha: You are paying for the extras. The Hero edition only includes the manual. The Champion edition includes wallpapers, almanac, map, ring tones, soundtrack, and documentary. The Royal edition includes all of the above, plus a collector's book, cook book, guide, concept art, and novella. You can see the full information in the description for each of the versions.

I think the basic issue is that GOG's usual marketing description doesn't quite match up with a game that's been released in three different versions with different goodies based on the price. I think the three release bit comes out of the original Kickstarter campaign, where different levels of funding received more or less extra stuff.

WebJunkie: The issue is the 'extras' are specifically stated as being FREE, and in fact are the reason for the 3 price points! Not only is that confusing, it's questionable practice!
