Generally, the game is good, but I expected much more from Bioware especially from a new DA game. What I liked were the missions on war table (although a 20 hour mission is too much in my opinion), crafting of armor/weapns/runes, update of potions/granades.
Some of the things that I did not like:
1. Awful AI for companions + no tactics to correct it and even when I give a direct command I don't always get the desired result;
2. Enemies often stay without attacking, take too long to react or run around aimlessly (even on hardest difficluly).
3. NPC-s on map do not help you in battles, don't care when you take out your weapon (and you can do that everywhere) and start shooting, and they also cannot be hurt so it feels fake.
4. It kinda gets tiresome and boring to collect herbs, shards, letters etc. etc. all the time. They could have reduced the time it takes to complete such missions and the resource misions could bring higher results - especually when on higher levels the making of a single potion takes 3 herbs.
5. Missions like chase a druffalo here, and a hala there and a special ram to the other side of the map - a "suitable" and "exciting" job for the inquisitor.
6. The main plot itself is rather short and there are no meaningful side quests (like the one with Connor or Dagna in DAO or even Merill's quest in DAII). The choices are very limited and the graveness of your decisions is not felt throughout the game - there is a lack of moral choices and so there is also a lack of emotional attachment.
7. Relationships between characters - romantic and otherwise - are flat. Dialogues are not good enough especially in the first part of the game. Again - there aren't many emotions, moral choices and even the cut scenes are not very good - e.g. the sloppy work of inqisitor and josephine kissing. The only relationship that was nicely made was between Cassandra and Varric.
8. The small skill trees (also the lack of trap detection, lockpicing, persuasion etc) + the fact that you are limited to only 8 skills + the possoblity to respec points all the time leads to very limited number of distinct class builds that you can actually make.
9. Too few and "cosmetic" upgrades of skyhold - even if they do not increase them, they should have at least made them functional.
10. There is absolutely no need to upgrade all of the characters because they are never required to fight together - there should be some point in upgrading all of your characters - both in terms of skills and armor. Now I can only upgrade 4 and leave the rest naked if I wanted to.
Well, I could go on, but I think it is already too much. Bottom line is - bad mechanics, bad dialogue, lack of intertwined and complex missions and moral choices, as well as limitations in skills and skill trees all make the game to feel less challenging, less addicting, fake and flat compared to the previous games.
