DAO is held up on a pedestal because it had 50 million different variations, variables and options. They did this because they wanted to make sure that in case the game was a One Off it would be a memorable experience. Had they known it would go beyond that one game, they would have never given us half of the stuff they did, because DAO is simply too massive, too varied, too unwieldy, and too customize-able for it to be properly adapted for future titles, because it wasn't designed with Sequels in mind. That is entirely Bioware's fault for making that design decision. That is why their design approach for this franchise has changed. They now see the series has staying power, and are moving to make it more manageable to adopt previous works into sequels. This is not a bad thing, it is frankly the opposite. Yes, Origins is a masterpiece, but even masterpieces have flaws. Unfortunately Origins primary flaw is that it was designed in a One Off fashion, not in a fashion that accommodates sequels. Same goes for the PC, this is why the HOF can never return. The options are too vast, too complex. The challenge could be met if they had unlimited time and budget, sadly they do not and thus we have this situation. Origins combat was slow, clunky, tactical (on PC, on Consoles not at all), and ultimately not fun to look at. DA2 was a typical Bioware response, they swung it too far in the other direction. Very fun to look at, not tactical value and totally ridiculous and over the top. They keep working at it, trying to find that sweet spot that eludes so many developers in the industry.
Origins also possess another problem (a problem as it applies to sequels). That problem is the blank husk PC. The old school style of PC that is designed to not be an actual character themselves, but instead be something the player projects themselves onto instead. This has it's own list of merits and drawbacks, and have been discussed to death. For the the purposes of this, and how it relates to the future of DA, it is a negative because they can never re-appear because of this. They were as silent as a graveyard, never had any facial expression of any kind, and for all intents and purposes, was just an avatar for you, the player. The Devs cannot possibly work with this. PC's such as this rely almost entirely on Head Canon and the players imagination. It is basically impossible for Devs to design around this and anyone who asks them to try that has no idea what they are actually asking. This is why Hawke and the Inquisitor are given voices, are given more "set" parameters to work with. There is less "fill in the blanks" for the players to do. This of course causes players who enjoy that to lash out and complain they can't RP the way they want. But many of these same people are the ones who want their PCs to return in some form in later Titles. These two things are mutually exclusive. If you want PCs to remain relevant to the IPs setting in some way in future titles, you have to accept some predefined aspects of the PCs. This is not a bad concept by default, contrary to what some fans might think of the issue.
So basically, in conclusion. Bioware never decided to "move away" from Origins. They simply realized that, due to their own design decisions of the time, there is very little they can actually work with that won't be cheap, ridiculous, hand-wavy or whatever else. I will always love Origins, it will always be a masterpiece of the video game industry. But it's time we move past this, it really is. Origins has not aged as well as it would have, had they known the Franchise would be a smash hit. They were limited by their technologies and their inability to see the future and realize the game would be a massive success. Being ignorant of that fact does change how you approach designs, it changes how you think and look at things. People have a tendency to look at the First of anything, Books, movies, game series, w/e and decide "The first one is always the best one." Sometimes this is very true, sometimes it is not. Sometimes the first one of something was created in a way where a sequel does not work without extensive alterations. This is a very common thing, look at Empire Strikes Back. If you know anything about IV and V you would know that IV was basically a entirely different premise, the characters underwent extensive rewrites and alterations for V. Many people consider V the greatest of the 6 movies. This really isn't much different. Origins is good, just as A New Hope is good. But A New Hope is a very different thing from Empire and Return, just as Origins is a very different thing from 2 and Inquisition. In both cases it was done for the sake of building Franchises, rather than a One Off. I am sure there will be many of you who dispute this, who insist I am wrong or whatever else, but that is how I see it. I will take the Franchise, over the One Off any day, no matter how amazing that One Off is. Thank you to everyone who reads this entire thing, and to those who Like it. That is all I have to say.
