Castrum: Two Worlds is one of the most atrocious games I have ever had the displeasure of playing. Awful graphics, awful gameplay, awful dialog, and so on. I'm normally the kind of person who is willing to forgive serious issues in a game as long as it is playable and fun, but Two Worlds hardly justifies itself in either category. And even with all that said, GOG wants to charge you $10 for this atrocity of a game? Do yourself a favor and spend your money on something that's actually worth your time.
Avoid this game at all costs.
So the op have only played the xbawx version, and apparently had some problems figuring out how to play.... it has to be the games fault then XD
I think most reasonable people can agree that a someone bashing a pc game on the basis of having played the sub-par console version isn't really an authority on the subject.
Having played both the xbox and the gog version of Two Worlds I can attest to the two versions being like two different games when it comes to both graphics and performance. They are literally a couple of worlds apart.
So, is the gog-version of Two Worlds a "Waste Of Money, To Say The Least"?
Not at all. Diffuse story and funky dialogue aside, the enormous game-world to explore as one sees fit and the freedom therein will probably suck you right in if you like such games.
Playability is solid, if one can grasp the basics of the game (the manual is a great help there if needed). The combat is as visceral as it is easy (hold down button, see sword dice 'n slice), the magic system is straightforward and easy to grasp (collect stacks of spell-cards to improve spells) and the stealth/archery is not all that different from other action rpgs.
But to address the playability-issue more directly: It is not like the game isn't playable, far from it, the controls do their job and the game is graced with years of patching that have fixed tons of bugs and tuned up the framerate. The basic elements of play, that in my opinion constitutes the overall playability, is well implemented. Character progression (stats, not story) is engaging and intuitive, the game-world is absolutely huge and well stocked with things to do, and the quests are entertaining enough even when muddled by the aforementioned funky dialogue.
Now don't get me wrong, Two Worlds is not the greatest thing since sliced bread, but it is still a highly playable action-rpg in its own right. $10 for Two Worlds is not a bad deal at all if one is looking for a rpg to play until the big guys pump out their monstrous productions come holiday season.
I do find it hilarious that the op implies that it is better to pay more than $10 just to avoid trying the game out.
Whether or not one finds the game fun is, as is expected of a game, a matter of personal taste (see the raging subjectivity of the op for an excellent example of this), but fans of action-rpgs that are between games at the moment could do much worse than picking up Two Worlds.
