Enter a world where your objective is painted on a map for you, rendering exploration a thing of the past and where a sense of the unknown doesn't exist, where you can instantly travel from place to place without effort or actually moving, where even your health refills itself so that you can stick to following the quest marker on your map! That world, is SKYRIM! What a joke, this is gaming for idiots.
I feel the above quote is quite pertinent to this topic. Although I do not agree completely with the above post it is still worth extended discussion.
Personally, I feel that the quest marker is the only true issue with the game being casualized to the point of hurting the core enjoyment of the game (barring auto-heal being faster than presumed). Quest markers in the game make it so that Bethesda essentially no longer has NPCs give full quest directions/discriptions and thus removing the quest marker or ignoring it are not options since it is impossible to finish the quest purely by NPC description. Not only does this remove the fun of exploration by making you mindlessly drag your feet to the next quest marker but it also hinders roleplaying by making it so your character magically knows where the quest item or boss is.
I believe this issue may be solved with a moderate amount of effort (although it is probably too late to fix now). First, and most importantly, all quest givers must give detailed directions in order for people to be able to complete quests without a quest marker. Secondly, there should either be a quest marker toggle in the menus or in the journal menu you should have the option to turn quest markers on for specific quests (thus you would not need to toggle the marker on for difficult quests then turn it back off after completion).
To clarify: I fully expect to purchase Skyrim and enjoy it for hundreds of hours. The intention of this thread is the identification and recognition of oversimplified game mechanics that many feel detract from their enjoyment of the game as well as constructive criticism on how these mechanics may be changed to appeal to all fans/consumers. Anyway, please discuss in a civil manner.
