I would love to see more complicated quests in Entropia (and as on the above picutre mixed with some actual knowledge based on cryptography and history and other knowledge).
There are games that actually have this piece of qusting an even more- talks with npcs are like old time games where you have to comunicate with them using words and sentences - the npc reacts on th words or talks that "he/she has no knowledge on what you are talkign about" if you use something he/she is not familiar with.
So nothing like:
NPC: "Bla bla bla bla...
You:
1) ---
2) ---
3) ---
If (1) NPC kills you
If (2) NPC gives you 1milion ped
If (3) NPC dialog continues
...
But more like:
you come and see npc:
You: "Hello"
NPC: "Hello, my name is Bob, i tell you those wolfs are gonna ruin our village... <mumbles>
You: "Wolfs?"
NPC: "Aeeeh... <spits>... if not the kings will not to hunt them i would handle them myself! Damn creatures!"
You: "Help"
NPC: "I am not sure if youngster like you could help but... oh well i guess you could try and go and talk with damn ruler of this land."
<quest log updated>
You: "King"
NPC: "Dont even mention that good for nothing King Richard in my house! Or i will have to kick you out."
You: "Richard"
NPC: "I have warned you! Stop it!"
You: "King"
<you get hit for 20dmg and get kicked out of Bobs house and can't enter for 1 hour>
...
NPC reacts on many other words i.e. names of other vilages, wolf realted topics, mayby on some secret words you need to find out somewhere else (i.e. from hidden script or from other npc).
Soudns fun isn't it?
And yes - games like that do exist already.
Problem with them is:
first solved and put on wiki - everyone just do the quest in "rush" way not enjoying it fully. So to pass this there would have to be some randomnes generated too (i.e. not all quests are avaible for everyone or for there are many different solutions for each person and not every possibilities are avaible for everyone.)
@edit:
some quests in those games are really complicated and not fully discovered yet (because i.e. there is wierd language involved) even though games exist quite long and many plaers tried to solve the puzzles.
