Skyrim's world is larger, more populated with diverse enemies and friendly settlements, and visually better. But I think Skyrim's shit combat really hurts it. Skyrim has more lore, but the relationships you build in Dragon's Dogma seem more personal. The feeling of mystery is also better in Dragon's Dogma and the final battle with the dragon blows Skyrim's final dragon battle away. I know I can't quantify it, and I'm not trying to make a pun on the game, but it seems like for all of its limitations when compared to Skyrim, Dragon's Dogma just has more heart and soul put into it.
It wasn't that Skyrim's world is larger, so much that a LOT what was originally planned for Dragon's Dogma, including its gameworld, didn't make it to the final cut. And I don't think Skyrim's enemies are more diverse, the ones I could remember off the top of my head were bandits, thieves, draugrs, those blind former snow elves, giants, trolls, small critters like mudcrabs.... idk, only some of the more iconic ones like giants and draugrs which I memorized the most, but the rest is just blurry.
Meanwhile, not only DD has the most diverse beastiary out there, especially if we include Bitterblack Isle (just this one dungeon utterly blows everything Skyrim has to offer), it even did exceptionally well by following Gothic's open world design philosophy of placing the more challenging ones in specific areas and certain regions, as has been mentioned. Its sudden miniboss encounter like when you meet a Cyclop or a Chimera in the middle of nowhere and the game gives you a quest to slay them are a whole lot more exciting than meeting a
dragon wyvern in Skyrim.
And Skyrim has more lore? I was like, "what the faq?" for a second, but then I think about it some more and, duh, Skyrim has 4 games worth of loredumps before it to draw from, and yet unfortunately for people who cared about Elder Scrolls's lore, Bethesda didn't. I heard that there exist those who even have PhDs on Elder Scrolls lore, and when Skyrim came out (or maybe even since Oblivion?) they pulled their hairs out of frustration with the retcons Bethesda did with it, especially the one that made the choices you've made at Morrowind completely and utterly useless.
Meanwhile, being a completely new game, and despite being cliche, I think Dragon's Dogma pulled off the 'cycle' trope much, much better, even better than Fromsoft could ever done with 3 Dark Souls and its many DLCs. Tbh, I think Fromsoft should've stopped at Dark Souls 1 and don't even think about making a sequel based on cycle trope. But DD, with only Everfall and Bitterblack Isle, was able to conjure a more compelling 'it's a cycle' narrative where Fromsoft failed with 2 sequels and 5 DLCs.
