Change is NOT always for the better, thats a major problem in the software industry in general, not just gaming. Companies feel they have to change things, just to sell a new product. Often the result is a new product which is worse. The clearest example currently would be Windows 7 to Windows 8. Microsoft had is absolutely nailed with Windows 7. It's an operating system which usually does what you want it to do in a reasonably clear and easy to understand way. Windows 8 is a nasty mess where they tried to cram two completely different ways of operating a computer into one experience, and people hated it. (Does it sound anything like the current DAI situation?). Versions of Mac OS after Snow Leopard also suffer from this same issue, but to a lesser degree. Instead of building on what they had and making it better - making it what people want - they went for "look how new it is!" and produced products which reduced usability in key areas that the actual USERS find most important.
For me, it's really the obvious lack of any concern for the PC player that annoyed me enough to get my refund. Will I buy it again? Sure, if they fix some of these fundamental issues.
But no, I fundamentally don't think Bioware moved in the proper direction with either DA2 or DAI, neither of which built on the best aspects of DAO that made it such a beloved game. Instead the concentrated on exactly the wrong things and demonstrated a complete misunderstanding of what made DAO great. I'm certainly willing to play it anyway, for the story and the characters, but not until they fix the broken control structure and camera.
Take just one aspect: DAO had fantastic aesthetics. Aesthetically it looked different than anything else, and had a look which complemented the subject of the game well. DA2 moved away from this and looked somewhat more like "any other game". DAI takes this a step further and now doesn't have anything aesthetically special or unique. Sure, both DA2 and DAI have better graphics than DAO, but not better aesthetics (DAI isn't even close). Take a look at this excellent (and short) explanation of the difference between the two: Aesthetics vs. Graphics.
After trying DAI I now firmly believe that Bioware would have been far better off using the DAO engine, with minor but important updates (like the ability to access reasonable amounts of RAM) and then giving us a series of great, emotionally engaging, memorable, epic, story-and-character-rich RPGs. They would have save countless millions on development and they would have built upon the core strengths of DAO and built it into a strong franchise. Their core user base would have grown and grown based on those strengths. We could have probably had a new great RPG every year or two, because nearly all the technical work would have already been done. Instead, they ended up with a game that just might have a good story in there somewhere, but with mechanics and aesthetics problems (along with other issues) which are so disastrous that they've ended up with this forum being full of disappointment, anger, and fury. Take a look at the user Metacritic reviews of DAO, DA2, and DAI, and you'll clearly see what people think of these "great changes" Bioware has made. It's a clear example of change being for the worse, although at least DAI is currently slightly ahead of the disaster that was DA2...
That I received a text that so perfectly expressed what I was thinking at the time made me smile!
