No... what? No to the similarities? or No to people liking Gothic III?
I see similarities (thats opinion of course) and I see plenty of people stating how they like Gothic III (just look in the Gothic forum here on GoG). People bash Gothic III... people bash Two Worlds.

I will wait for a promo to purchase this one, wishlisted.

Not a bad game, not a masterpiece. I already own it and never got to finish it. The graphics are nice, even if the HDR is largely overdone : when the sun reflects on the water, no problem, but when it reflects exactly the same way on a dusty mountain trail, blinding you, now that's a problem.
In fact, the main problem of the game is the combat system: there's a very good idea there, the little back step you can do to avoid being hit. While it is a very interesting feature, tactically speaking, once you've mastered it, you'll hardly get killed by anything. I was able to take down much stronger opponents just by observing their attack patterns, adjusting my back step and my strikes to it. It's funny at the beginng, it is boring very quickly.
It's another matter with ranged weapons-holding ennemies. Those ones will really get on your nerves, as you will very often think their arrows have a heat-seeking device. Sometimes, you won't have any clue how, but they will strike you each time...
The world is nice, yeah, pretty good viewing distance and a clever blur use, like in Gothic III. The thing is, as far as I like Oblivion, I still prefer "non open world" RPGs like The Witcher, Baldur's Gate and the likes. Why ? Because in an open world game, most of the time you can safely ignore the main quest with no consequence at all on the story.
So, Two World is a game worth the try, especially at this price. But it's not a gem, either.

You mean someone has made an RPG where archery isn't shite? I'm now interested. Archers are good in Dragon Age: Origins Awakening but it means playing and importing from Dragon Age: Origins where archers are shit.

Really? Maybe we played different games. I am thinking of lines such as the following, which one endures countless times in the course of the game:
"Nature's SERVANT awaits!"
"Somethin' on your mind?"
"STOP TOUCHING ME!"
They sound to me like the developers gave the microphone to their kid brothers and sisters.

Plenty of games have great archers. Neverwinter Nights and Titan Quest both have some overpowered archer builds. In Daggerfall you can get to the point where 1 arrow kills just about anyone as well.

I know you've already clarified on this, but I'm quoting because I'd like to directly comment on a few of your statements.
I don't see how people stating that they think it is a good game is any less "fair" to the readers than you telling them it is mediocre or terrible. Frankly, if anybody is relying solely on the opinions in user comments and reviews to decide whether to buy a game or not, then it's their very own fault if they end up making the wrong decision. Apart from judging the objective quality of the game (technical execution, etc.) the only thing a commenter/reviewer can do is give their opinion and give well-founded reasons on why they have them. Readers will have to decide for themselves what they are looking for in a game and whether it might suit their tastes. Any game that finds its audience is "good", and Two Worlds in particular has a sizeable community of people who truly enjoy the game. (If it didn't, I don't think they would have made a sequel).
As for your specific points of criticism: I can't comment on the voice acting because I played the German version, where it was okay. I'd sure appreciate if GOG would start making use of their "Languages available" field one day, I don't think I've ever seen a multi-language game release here yet. If the acting is really so terrible, people who understand German (or one of the other languages the game has been released in) should be given the choice. The story and quests are not really original, I said that much in my own review, but I don't think that makes them terrible (I couldn't remember any Action-RPG from the top of my head that had an interesting story). And I can't see where you would find a lack of atmosphere, to me the excellent atmosphere was what made the game memorable. And for the most part the game is as difficult as you want it to be. The focus is, after all, on exploration.
So you are less into the "very freeform" kind of RPGs that make you choose your own game and don't offer much in the way of a clear goal. That's a valid and justified point-of-view, but so are those of the people who loved the game. Both sides have right and reason to state their opinion. The only important thing is to back up your judgements with clear reasons so people can make up their own mind.

Generally I've found the bargain bin retail copies of games will be about 5 bucks. To me, getting the game without the DRM saddled to it is worth the extra few bucks. I'll probably pick this one up.
As to those lamenting this game is too new: who cares? It's another game in GOG's catalogue and in no way impacts anything else. I say great. Keep 'em coming.

"This pack contains the original Two Worlds along with two expansions: Tainted Blood and Curse of Souls" <- Please add the version number there, in the gamecard.
Nice, GOG. I'll buy it just because it is open-world, comes drm-free, pre-patched and with the two "expansions".
Now, we need Gothic 3 fully patched on GOG. ;)
ArcaniA: Gothic 4,
Two Worlds 2,
both coming out this year.
I guess you should play Morrowind/Oblivion first, before getting your ass kicked in the other mentioned games.
I'm willing to play Spartan: Total Warrior and Viking: Battle for Asgard, too bad they are for consoles only.
Totally agreed with those two sentences.
I'm not saying that Two Worlds is excellent, I've never played it but I will. Just agreeing that some 2,3,4,5 year old games are already hard to find and aren't available on digital stores. So finding such game on GOG and drm-free, is a bonus for the gamer.
When... When game publishers will wake up?

Hammerfall, you're cool.

Because of all the griping of what belongs on this site and doesn't (I wish every game ever made would be archived here; crap or not), I'm going to buy this right now. The negative comments have actually sold me.

Well, when the NPC shoot at you, they're damn good. I've tried to answer them back and found the archery system interesting but not really easy to deal with... I quickly abandoned it for the old-but-efficient "run, scream and slash" method. ^_^

You can get his game for 90 cents at gogamer.com right now for 48 hours

Does it have the DRM removed? If not, it's probably not worth it, unless you're only going to install once/don't mind begging on their forums for activations back in the event you run out.
