Playing Skyrim regret-free

What's amazing about these open world games is the freedom I have as a player. If I don't want to follow the main story line for a while, and just explore, I can do that, and the game won't break.

On the other hand I don't particularly like the feeling of having made a significant, bad choice in the game, among the lines of Yeah, that dialog option you selected hours ago? This amazing quest line is now off limits.

If I recall correctly, in Morrowind, I had to progress through a few different guilds' quests in the right order, otherwise it'd have stopped my progress in a few guilds.

As a Skyrim example, it doesn't appear that the very first choice made in Helgen at the very beginning has much significance. If someone told me It's not that significant, you still get to choose sides (or, rather not told me "This is important"), that'd help.

Another example: Based on a question I read here, I should probably make sure that I don't throw away any of the dragon priest masks and need to make sure to collect one during a specific quest. This would be relevant for this topic if I could easily miss it otherwise while doing that question.

This includes accidental problems possibly caused by bugs: It appears it's easily possible to lose the option to buy one or more of the houses due to bugs, and one needs to be careful about the order of playing through some quests.

It doesn't matter too much which of the love triangle guys in Riverwood I support: That's not nearly significant enough.


Are there non-obvious, hidden decision points in the quests and story lines? When playing in a certain area, doing a certain quest, what do I need to make sure to do or not do, to not accidentally prevent me from getting or achieving something significant?

I still want to explore on my own, but want to be aware of which choices are important.

This is somewhat related to that question.


The UESP wiki, 'Quest Timing' article has a detailed list of quests (and notes about those quests) that will have a significant impact on other quests and the game, in general. Some of them are due to bugs, and some are because they are designed to be that way.

It also recommends if a quest has to be done early or be postponed before/until another quest has been finished or another game event has happened, to prevent bugs or a negative impact on other quests, or the game.

The whole article is too big to be included here. I'll be adding some of the most notable quest categories and the quests under those categories related to your question:

Quests to Do As Soon As Possible

  • Blood on the Ice
    Why: The Necromancer Amulet is a Legendary-quality item very useful for low-level spellcasting characters, especially those interested in Conjuration, and can be sold for a lot of gold for a low-level character. There are numerous glitches associated with this quest, and the best fix is to start the quest as soon as possible and complete it all at once.

  • The Forsworn Conspiracy and No One Escapes Cidhna Mine
    Notes: ...if you side with the Stormcloaks in the Civil War and if you complete Forsworn Conspiracy before Compelling Tribute and then wait until after Compelling Tribute to start Cidhna Mine, it will become unavailable permanently. It is also possible to have the same effect result from completing Forsworn Conspiracy, then completing Season Unending before Cidhna Mine, even if you have not joined the Stormcloaks.

Quests to Save for Later

  • Dragon Rising
    Why: Completing this quest early ensures a large number of Dragon Souls by exploring, if the player is capable of surviving the dragon's attacks.
    Why not: After completing this quest, Skyrim will be full of dragons. Deferring it until you're in the mood to fight dragons lets you explore the world in relative peace and allows you to learn Words from Dragon Lairs more easily. Note that starting the quest will not cause dragons to appear; only after killing Mirmulnir will dragons start spawning.

  • Joining the Stormcloaks or Joining the Legion
    Why not: Joining either the Stormcloaks or the Legion removes access to all the opposing faction's camps and causes "random encounter" fights to occur. Capturing towns has been known to break certain quests.

Quests that Conflict

  • Lost to the Ages (Dawnguard DLC) and Mourning Never Comes
    Why: During Lost to the Ages, you are required to trek through Raldbthar, where Alain Dufont lives. If you kill him before starting Mourning Never Comes, you cannot kill Nilsine Shatter-Shield for the bonus reward in that quest.
    Why not: Alain only becomes hostile if you attack him, he won't defend the other bandits in the area. You can kill all the bandits but Alain, and complete Lost to the Ages without affecting Mourning Never Comes. Also, Mourning Never Comes is only available if you choose to join the Dark Brotherhood; if you choose to destroy them, you will never be given it.

The only major example of this that I can think of is that there is a segment of the main quest that is skipped if you resolve the Civil War prior to reaching it.

Similarly, your decisions during that chunk of the main quest can allow you to skip some of the more repetitive fort-conquests during the civil war if you play your cards right.

Other than that, and the obvious mutually exclusive choices (Stormcloak/Imperial, Blades/Greybeards), there shouldn't be any other dead ends.
