Now I am an immersionist sort of player who does not like a GPS like system in Oblivion, so quest markers are off for me.
But many Oblivion quests rely on you trying to find an NPC. Or you just want to know where Thamriel of Tamriel is in the morning. Due to the Radiant AI, many NPCs have schedules that take them to different cities and places across Cyrodiil, and you are trying to find them to no avail without any magic-quest marker.
So I thought of a idea, that may or may not be feasible, borrowed from Daggerfall.
Idea follows:
Suppose you are searching for a particular NPC in a city. You don't know his schedule, but just his name. You should be able to go to the tavern (where the owner may know almost everybody in that city/town), and ask him about a person (by choosing a dialog option - "Ask about a person"). Then you type in the name (this may be tricky - does Oblivion support typing in-game? I have seen Kyoma's Journal mod do it, but that is in a book). If you spell it incorrectly, the tavern keeper will respond "I don't know anybody by that name. Maybe they frequent a different tavern." if he likes you, or "Piss off, don't bother me" if he hates you). If the name matches something in Oblivion's database, the tavern keeper can say, "Yes, I know [him/her]". The tavernkeepers they can decipher their schedules from Oblivion's database (is their one, like TES4Edit does) and tell you ("I believe __ goes to the [temple/arboretum/etc.] around __ pm, but I may be wrong.") . It has to be random, sometimes the tavern keeper will say that they don't know that NPCs schedule ( "___ doesn't frequent this tavern, so I don't know [him/her] well enough.").
Tricky parts are:
1) Can a name be typed in a dialog menu? If not, is there an alternative, like Kyoma's Journal mod does it?
2) Can the NPC name and schedule be deciphered on the fly, or is that something that can be done offline via the CS and/or Tes4Edit only?
Any comments/ideas/suggestions?
PS: Unfortunately, I don't know enough about mod-making to even imagine taking this up... But thought the idea could be implemented by someone smarter than me if they have the time and inclination.
