Pillars of Eternity was a game that, to me, felt similar to DA:O. Not everyone shares the sentiment, but if you haven't heard of it, I'd recommend at least watching a review of it.
I really hope you'll enjoy it! The sequel, West is also good, though a bit weaker than East.
I don't often reread books, just because I would rather spend my reading time with a book I haven' yet read, but East is one of the few books I've made an exception for; I must have read that book four or five times by now.
I might be a bit of an outlier, but I am not at all a fan of crowds, so I strongly prefer concerts with assigned seating. I'm in a relatively small city that rarely ever gets big names, but even when we do, most of our concert venues are primarily standing-only, with very few seats available and even those are first-come-first-serve. So I try to always get there early enough to ensure a seat. I just want to see my favorite artists perform live, not get jostled around and smothered by strangers.
So, for me, the cliche answer is Lord of the Rings.
But another book that I've always really loved, is East by Edith Pattou. It's a very simple fantasy story, but I read it when I was much younger and it's always just felt very comfy and cozy whenever I read it.
