All right, so, in preparation for Inquisition, I have finished the original game, Awakening, Witch Hunt and am now mid-way trough DA2. I think I can do a bit more in-depth comparison now, which does make me happy. (Now when I finish that, I will make another attempt to understand what people like about Dark Souls, but that pretty much seems to be a lost case :-P)
I'm fairly sure now I get the wave of hate that game rose amongst the players, no matter how justified it is - I mean, anyone spewing fire and going how DA2 is the worst RPG in gaming history should probably try and get things into perspective, because it really is not. But more to that later.
Let's start off by saying that when I have booted DA2 after finishing Witch Hunt, I wanted to just turn the game off and give up - the fact that I loved -something- about it previously kept me playing, however. Now, why did I want to just give up? It was just so different from the original. Every time I clicked a dialogue responce, there was some person who started talking and it was not a response, pausing combat and switching between characters just seemed to make combat longer as opposed to easier and more tactical, no items in the game had any reasonable descriptions and all the lore I found was basically just stuff taken from the original game - not even talking about the fact that the game quite literally only has a single dungeon for all caves, all it does is to place barricades and start you off at different locations so it's not exactly the same. That's bad. That's really bad. That's pretty much all the values of the original down in ashes.
... But then, based on my previous experience with DA2, I gave it another chance. And suddenly, the whole real-life day passed by without me even noticing. The presentation and writing in that game - it's top-notch, from the main storyline, to all the side characters, along with presentation and overal approach to the story. DA2 completely breaks the traditional bioware 'rails' of Character is THE hero, you get three quests at the beginning, you join a powerful organisation etc. It offers a storyline which starts off very small, offers a unique look on the game's world trough the eyes of a commoner, and then allows you to move up trough the ranks of the city. It's not a heroic storyline, for sure - but it's a unique one, especially in videogaes. And the much smaller scale gives the game chance to evolve stories it tells, and a lot of sidequests have continuations in later acts, which get directly influenced by your previous decisions (what is up with people saying you get more say in Origins anyway? All the quests I have played there got resolved immediately upon finishing them and the only thing you could influence was a couple of companion decisions and the ending), it's just ... Really good in this aspect. I suppose the game could work even better if it was basically a Telltale storytelling experience, but... Eh, we got what we got, and it's 70% dialogue anyway. Yeah, sure, you don't get much say in the ending, but... I don't mind. It's refreshing to not have the main character allpowerful, and you get a LOT of say in how your companions behave and in what happens in the longer-lasting questlines in the game.
Sooo... In the end, I think that the best game in Dragon Age series was Awakening, closely followed by 2 and with Origins sort of tangling behind them all. That is all. I have more that I want to say, especially the excellent character banter in DA2, buuut... Oh well, I'm too lazy :-P
