It was a decent game for the time
No.
I was promised to be able to enslave nations using powerful necromancy. They have failed to deliver, and I shall forever disdain them.
Not to mention their unabashed plagiarism of Warhammer Fantasy regarding daemons and magic, the Derp Roads, level scaled encounters AND poor enemy variety.
Camel, what do you disagree with? Do you deny BW made false promises? Do you deny they commited plagiarism? Do you claim the Derp Roads were enjoyable? Or that the encounters did not scale to the party level? Perhaps you would like to compare and contrast DAOs enemy variety to that of BG2, or even BG1?
I don't think DAO was great but I think the plagiarism accusations it gets aren't good criticism.
Plagiarism in fantasy is inevitable because all the basic tropes were already established centuries ago and every since author since early modern times has aped what someone else already made. The difference between inspiration and plagiarism is putting your own spin on it.
Dragon Age rips ideas from Game of Thrones, Twitcher and Warhammer but it uses said ideas better than any of those three things. It manages political intrigue without every noble being cartoonishly evil like GoT, it's unfortunately liberal but never preachy about it like Twitcher and it's dark but not retardark like Warhammer.
It also has a take on dwarves that AFAIK is unique and is probably one of the best fantasy dwarf depictions there is.
Those ideas still aren't executed particularly well at any point but I'd argue it had the potential to be better than most of what it was copying and could've developed it all into something greater. That potential was then spit on, pissed on, shit on and shot.
