It's a tough one.
I have similar feelings to both games really. To start off, both are huge worlds and have tons to do, see and explore. Though this also put me off from both games even though I enjoy playing them when I can. Everything feels like a chore and I get distracted far too much. I'll go one place and try to do a quest and I'll find a location (or two, or three, or four) on the way and, from those locations, more quests until the point were I've got a quest-line that looks more like a book.
I dunno, kind of felt to me that Fallout was about the same. I keep wondering just how crazy Fallout 4 is going to be.Trust me, I love open world games and large RPGs and I've sunk 100s of hours into the Fallout franchise, but I just can't seem to get into these two enough to the point where they become favourites of mine. I felt like the Fallout games had a better balance with its overworld and things to do without me just getting uninterested in exploring or completing quests.
One odd thing about the turn-back borders that irritated me is how sometimes Geralt would actually be excited and enthusastic about what lies beyond despite turning back. The only times he really seems to complain about it is if you hit a turn-back border while swimming at sea, where he'll complain about being too old for that kind of swim.Though above is my only real gripe with the two games and something that's more so a personal preference than anything else. So which one's better? I honestly couldn't choose. Skyrim had a better overworld in my opinion with more dungeon-like areas, while the Witcher did become a tad repetitive with its locations (also I really disliked the borders in the Witcher were you had to turn back and how it had separate overworlds too).
So much yes. It's so much better it's not even a contest. Witcher 3's soundtrack dominates. Might even be my favorite soundtrack ever.There's no doubt about it though, the Witcher has the better atmosphere and soundtrack to accompany the amazing graphics, which give it this dark fantasy feel.
Here's an example:
Story's going to be more opinion base. But generally Witcher 3 has a better overall story that is more compelling and as you said, personal. Skyrim more so encourages you to imagine your own story in your head, with the story that exists in the game as only a framework to build your own around. So they kind of serve a different function in that regard.Combat is a tough one as well, the Witcher 3 definitely feels smoother and more tactical, but the weapons and abilities that Skyrim had kind of made it more enjoyable in my opinion. Story (though Skyrim seems to have a deeper more interesting lore), I'll have to go with the Witcher since it felt more personal and not "I'm a dragonborn and special" or "which side should I choose". One had more choice, but former felt more compelling even though I haven't completed it.
