Phew! I've just completed the game and may I say it's beautiful. Also, the game is VERY hard. You can't choose a difficulty level, so you'll have to play at the game's "default" and only difficulty level. Common enemies are usually only hard when they're in packs, but bosses... Let's say bosses are TOUGH. There are a few boss opponents that will require you to think of some unusual tactics, because there's simply no chance you'll handle them going head-on. And yeah, bring A LOT of healing potions to final battle. I've just finished it without a single potion, and it's been a REAL STRUGGLE. Two hours or so...
Game's core RPG mechanics is so much like Neverwinter Nights that sometimes you almost feel like you're playing NWN. I liked the mechanics. It's a pity you only get to buy good spells after the middle of the game, I'd like to see more spells and get them faster. By the way, you can increase character's skills (spend your experience points) at any time. This makes levelling up pretty much useless. And having to buy all the spells and active skills makes levelling up even more useless... I didn't like that. In Neverwinter Nights, you receive spells and skills as you gain your level. Here, in Drakensang, you receive experience points and increase your skills, and levelling up is just... Levelling up. That's pretty much it. "Player has reached level x", and that's all, nothing more happens.
I enjoyed the main storyline. There's plenty of side quests, and they are ok, and the main quest is great, and soooo long! Completing the game took me 45 damn hours... But it was worth it. Some of the plot twists were somewhat unexpected. However, the main storyline is solid, but it's not a masterpiece.
I liked the world, graphics are awesome (considering the game is 4-5 years old). Characters are great, I liked my companions and it was somewhat sad to finish the game, because I realized my adventure with these characters is over.
By the way, there's no fast travel system in this game, so you'll have to walk through the huge Drakensang maps on foot. Well, it didn't bother me.
And the dialogues. I've read a bunch of reviews before buying the game, and almost every single one of them said the game has awfully written dialogues. Well, I have to admit that sometimes you hear or read something funny, and dwarves speak with significant accent. However, those facts create unique atmosphere. Nothing feels uncomfortable, nothing feels out of place. So if you're afraid of possible flaws in dialogues, don't be, they're OK.
Overall, if you like old-school RPGs (pretty much like Baldur's Gate, Neverwinter Nights or Dragon Age), I think you'll really enjoy this game. Buy the game on sale, and it will be totally worth every cent spent on it.
7.5 out of 10.
