i share many feelings with the OP, but will always say i love bioware/bioware games... i just still feel like DAO is still the best of the trilogy, but it's also my number 1 fave game of all time!!!
i feel like DAO was a perfect circle of joy/fun. like a perfect TV series/novel.
DA2 was great at a few aspects and horrible in others, but still really enjoyed and played it a bunch when it first came out.
now DAI is kinda like taking some of the good aspects of DA2, and then trying to paint this big beautiful world but at times instead of using a detailed brush, the devs used "broad" brush strokes. for me, it's the little things/details in games that does it for me... and i feel like DAO had so many of those things nailed down perfect, to a science!!!
perfect example, just look at the stats in DAI and compare them to how theyre handled in DAO...
it's kinda gross, in DAI you sky rocket 2 or 3 important stats for your class, then the rest are THROWN AWAY///USELESS!!!
while in DAO every stat meant something to every class!!! it was all important!!!
another great example is the armor in DAO compared to DAI. while i enjoy the look and being able to ID the characters of Inq. and i do like the fine details of tweaking boots, gloves, helms etc, DAO had 7 realistic tiers of materials!!!! not to mention RACIAL armor styles and goods, it made the world feel SO LIVED IN!!!
you know, IDK if it just comes down to, do we want to wait 7 years for a perfect game? (DAO) or wait 4 years for a really fun game with a few flaws...
but there's just so many things DAO does for me personally, that make it that one rare game that it's perfect!!!
