Apparently the developers ran out of money and it shows - the game is unpolished to say the least and ends at the beginning of the story. Trine 3 is also easy in a very bad way - first level in Trine 1 was harder than this whole game. Buy only if you're a huge fan of Trine or if the price drops to a reasonable level - and I think 5€ would be asking for too much.
This game is horrible. I wanted to like it, I really did. Gothic 1 was a nice, goofy RPG and even its quirkiness and archaic design decisions didn't stop me from having a blast. I heard that Gothic 2 without the expansion was just like Gothic 1, but bigger and better. Now, Gothic 2 WITH the Night of the Raven... is just terrible. Awful. Mind-numbingly bad. Apparently the community complained that Gothic 2 was too easy, so the developers listened and made this steaming pile of elephant ****. Imagine Gothic 1 but you can't progress through the game because the difficulty is increased tenfold. Night of the Raven throws balance out of the window. Player character has barely any stat points in the beginning and even the weakest weapons require an absurd amount of strength/dexterity. As a result, fighting anything more demanding than a bloodfly or a wolf is just impossible as you will get killed while dealing no damage to the enemy. Damage doesn't matter because the entire fighting system is based on critical hits. You get critical hit chance by spending skill points - the same skill points that you could be spending on, you know, stats? By the way, enemies can crit too - you'll know when you get oneshot out of nowhere. Totally fair, right? The first half or so of the game is spent entirely on running errands for annoying NPCs and backtracking while avoiding enemies. The quests are bad and the story doesn't matter. Then you hit a wall and most likely have to google that you're supposed to finish the entire f***ing DLC to go on with the storyline. Which can't be done, since you can't fight anyone. The way I see it, the only way to finish this damned game is to grind for countless hours to even have a chance. The controls and the story are just as bad as in Gothic 1, but they make no difference in the bigger picture. I have no idea how Gothic 2 Gold Edition got so many 5 star reviews. It's archaic, it's unfair, it's boring. Don't play it even if you get it for free.
