Skyrim is none of these, in my opinion.
Skyrim is not an "Open World." There are places throughout that one can NOT go without some kind of "qualification" being met, like a quest. Open World means "open world", not "kind of sort of open world."
Skyrim is NOT a "sandbox." You can not change the world scope. Ever chop down a tree? Do those piles of wood get smaller as you chop firewood? Can uyou build a house anywhere? Can you decorate a house in any fashion you desire? Other than Helgen, which cities change as you play the game. I mean CHANGE, not just until after you sack Solitude or Windhelm, then all is back to normal. Can you dig holes in Skyrim? When Dragons attack cities, which buildings get burned to the ground?
Skyrim is NOT an "RPG." Can my character clap when a Bard plays their songs? Does my character eat and drink with animations, or just a click an icon in the inventory screen? When my character quaffs a potion, what happens? That is character actions alone. Do the NPCs really care what my characters does in the game? When I run from Riverwood to Whiterun after escaping Helgen wearing my Stormcloak gear, does that Imperial "prisoner march" care that I am wearing obvious Stormcloak gear? Do ALL those assassins that whats-her-face send after you drop the armor they are WEARING? After she dies, do they stop?
Now let's look at dialogue. Can you insult NPCs? They sure can insult you. Can you flatter them? They sure can flatter you: "It's a nice day with YOU around." Other than guards wanting to arrest you, can you bribe NPCs to like you better? Speaking of "liking you better," do you have a reputation in Skyrim? Not like in previous ES games. Sure, there is teeny tiny part where someone may gift you something because you are considered a "friend", but where does that show up? How does a player influence this?
Skyrim is an Action Adventure game. Nothing more.
I disagree. Skills are everything in an RPG. That is what you build character upon. In Skyrim, skills really do not matter much, especially for factions. The only skills that make a difference are, of course since Skyrim is an action combat game, the ones that allow you to kill more quickly or mitigate more damage.
Then there are the 2 schools of thought with role playing in video games:
1) "the player" has the skills in the game.
2) "the character" has the skills in the game.
If you like that *your* skills are used for picking locks or swinging your axe, you are in the first group.
If you like your *character's* skills are used for picking the locks or swinging your axe, then you are in the second school of thought.
I am in the second school, the character, not the player, has the skills used in the game. This means Random Number Generation (RNG) is used and checked against the character's skill plus whatever bonuses may apply. This, to me, is the ultimate in roleplaying. I am playing the role of my character in the game, NOT playing ME in the game as a pixelated version of myself.
Why do I NOT take any lockpicking perks? Because *my* skill is sufficient to open any lock in the game. Why do I ignore the Speechcraft skill? Because it is so underused in the game it makes very little difference and I can use those perks for my killing skills, which is what 90% of Skyrim is all about.
I fully understand the other school of thought and appreciate why players like that. I just enjoy my time better being someone else in computer games
I don't want to seem like I am picking on you, Jusey There are just so many players that have a big misconception about role playing in computer games that it needs to be addressed. Very basically stated, roleplaying is what happens in the game between the character and the NPCs that populate it. It has nothing to do with the "in my head" remarks. That is "pretend,"
When a player pretends, even Doom or Tetris can be a role playing game, by that definition.
"I am box loader packing the back of a truck," when I play Tetris.
"I am a Vampire," when playing Doom.
Do you see what I am getting at?
