My review will be separated into different parts covering the many different aspects of the game. First I want to mention that I beat the game in exactly 39 hours (107 days total), I did all the main story quests + many side quests I would say that I have probably done 65-70% of all the side quests.
Story: One of the most immersive storylines I have ever played. I usually have trouble following long storylines because english is not my native language, but I had absolutely no trouble following this one and understanding everything that the game wants me to do. This is the best part of the game, 10/10
Freedom of choice: The game will often ask you how you want to go about doing centain things, like picking a side for example. Infact you have to make so many choices that the game would completely change if you play it a second time. The choices play a big part on the story and I will definitely do a second playthrough in the future just to see how different the game will be, 9/10
Free roam: This is a very big downside in my opinion. Every chapter has it's own "place of operations", you are confined to only one place where you have to do your quests in order to advance to other sections. The places are big, but get boring after you walk around the same street a 70th time, 6/10
Gameplay: The fighting mechanics at the start were incredibly annoying. They were so annoying infact that I ragequit a couple times because I didn't understand the proper way of using them. Way into the game though I really saw the appeal of them. Having 10+ enemies coming after you means that you have to do a lot of fast thinking, changing combat styles and using different potions. So the fighting at first seems primitive and annoying until you get used to it, then it becomes amazing, 8/10
Graphics: Amazing graphics for a 2007 game. The greenery especially is beautiful, 8/10
Misc: Not being able to jump and walking off half a meter ledges is very frustrating. The game is full of invisible walls and really slows down your movement. You have to often guess where you can walk. These limitations are the worst thing about the game and the reason why it is not my GOTY of 2007, instead it will take the 2nd place in my list, 1/10
That's it for the review, I recommend the game, I payed 2 euro for it on the summer sale, but would have gladly payed 10 euro if I knew how amazing it was. Final score 8.5/10
