As I write this post, I finished my first playthrough of Dragon Age: Inquisition. I’m actually kind of pleased that there’s plenty of content I missed (because the game tricked me, but whatever). I’ve uninstalled it for now, but this is less a function of the game being bad (which it wasn’t) but my SSD being somewhat small. There are choices to be made, alas. I can definitely anticipate a second playthrough; I might even go back and play DA 2 again.
Overall, the game wasn’t overly challenging. That’s not a bad thing; every game doesn’t need to be impossibly hard. Some fights were extremely tough, but most of them were, if not “easy”, then at least very manageable. Of course, I played on the default settings, so your mileage may vary. It did have plenty of meat to it, of course — I ended up with 70 hours or so for my first playthrough, and I can easily see where people could rack up hundreds.
As far as a pure open world, there is something lacking, as the game is a series of set pieces, like Dragon Age 2, but far larger and far more varied. Some of the individual areas are somewhat small, but others offer quite a bit to do. There are plenty of fun call backs to DA: Origins and DA 2; some characters will reappear, one of them playable (Varric, from DA 2). The Dragon Age Keep has you keep track of everything you did in DA Origins and DA 2, and even if you haven’t played them, that’s okay, because you’ll set up things your own way or use a default state.
I can’t reveal too much without spoiling the game, of course. A lot of the characters are terrific and very well done; only one actively irritates me (Vivienne). The banter is very good, but could be more frequent. Plenty of romance options, if that’s your thing. People have written on the ending (well, the post-credits ending), which makes it clear that there is either a) a major story DLC coming (and Jaws of Haakon isn’t it) or b) another Dragon Age game in the future. I liked it, didn’t see it coming at all.
Overall, I enjoyed the game; it’s maybe 90% as good as Origins and 110% as good as DA 2. I recommend it, highly; it’s more fun if you’ve played the first two, but it’s also a pretty fair entry point even if you haven’t.
