Dragon Age Inquisition’s biggest flaw is an odd one: there’s just too much stuff. Too many areas (that are too large), too many quests and stuff like that. So the major step to enjoy the game is to get used to not completing every little thing.
Get past this and you’re left with a great game which (in true BioWare fashion) is helped immensely by very likeable companions. The main quest and bigger side quests are engaging, and the main quest for each area is usually also enjoyable. Sticking to the quests you find more interesting will also give you more than enough experience to go through the main story.
The combat in Inquisition is closer to that of an action game, with a more tactical “pause” system being available (admittedly I didn’t touch this as I’m not a huge fan of that style of combat). I found it engaging, even if most of my enjoyment was due to the story. Having a lot of choice in the character creator (after only being human in Dragon Age 2) was also pretty awesome.
