This game was a pleasant surprise. I bought it mostly because of the bargain price, after reading mixed reviews, and at first was a bit put off. It's a tactical RPG, much as Baldur's Gate was, but allows less freedom in terms of dialogue interaction with NPCs and uses a completely different rule system. At the start it's rather difficult to figure out what skills you should invest in, since if you are like me, this is the first time you have played using The Dark Eye ruleset.
As I said, at first it didn't impress me much, and its limitations surfaced almost immediately. Buggy pathfinding, run of the mill quests, flaky camera, nice but previous generation graphics, unconvincing bits (things like lockpicking right in front of the owner of a chest, or barrels filled with all kinds of goodies, a la NWN).
After a while, though, I got the hang of it and was able to refine my main character and the rest of the team in a way that allowed me much more tactical depth. You can invest experience points into skills and spells at any time, not just when you level up. You gain experience and levels Baldur's Gate-style, not Diablo-style, meaning that you don't gain 100 levels and you don't get endgame weapons that deal 100 times as much damage as the ones you get early in the game. Instead, the difference between a certain weapon and a superior one rarely goes beyond a few damage points or a slight attack bonus, but in the end it works out fine with the TDE ruleset, just like it does with the classic D&D one. So you can expect more fun after a few (or several, depending on how you play) hours of gameplay, as new possibilities open up. You can choose between a varied assortment of companions, up to three at a time, so that you can appropriately complement your main character's capabilities and weaknesses, whatever starting class you choose.
While the story may not be incredibly original in itself, it's not worse than those found in the majority of RPGs I have played, and it is well delivered throughout the adventure.
In the end, I highly recommend this game. It's not perfect, and yet I give it the max rating because of the enjoyment I got out of it. While there is room for improvement in several side areas, the basis of the game is solid, and I never got bored. Moreover, they chose not to implement a remote activation system to limit your fair use of the game, and in a PC gaming scene consistently moving towards the use of Steam or SecuROM, I really have to applaud the choice.
