Finally finished this. I give the game a 7.5/10 but it had the potential to be 9.5/10. The main problem, as I've mentioned, was the filler. I ended up spending too many hours fairly early on in the game doing side stuff away from the main mission and ended up losing interest in what was even going on. Then, by the time I got back to the main story I had a very hard time getting into it.
I played the bulk of the game on hard. The last three missions I did on easy difficulty (so that I could finish it on level 18) and skipped 100% of the dialogue. I just wanted to get the game done.
Too much of the game was a grind and this is bioware's fault. I only ever made about 20% of the potions, all I ever bought was one schematic, elfroot, dawn lotus, and skill respec. I don't believe I ever bought anything else. I barely upgraded weapons (far too convoluted). I upgraded nothing at skyhold. I'd say I closed no more than half the rifts in all the areas. And realize, I still played 50 hours. The game demands too much time repeating the exact same tasks with different textures of the environment around you.
The oasis level, to the best of my recollection, was literally worthless even though I spent a few hours on it. I could have completely skipped it. Other sections like the hissing wastes or the snow one I barely touched at all. Bioware completely failed to tie them into the necessity of the game.
A deeply flawed game which I believe was the result of too many people having their say and it lacked the direction of a central visionary. Ultimately,
in Bioware's goal to make a massive RPG we ended up seeing a massive amount of arbitrary filler instead. This is the wrong way to create an epic game.
The game should have used power properly. Basically opened up the final guy very early on in the game but if you try without enough power you get hosed. Try with maybe enough, maybe it works. Build up a huge army, it works out better for you. Encourage buy-in for all the hours that were otherwise wasted closing rifts and completing astariums.
I hope Bioware knows how to take this criticism and do better. I will grant they fixed up the linear tiny world of DA2 to a large extent, but they ended up swinging way too far to the other side. XB1 user rating is 6.7, PS4 is 7.4, but both are still well below critics'.
