Something i would like to see too, is if someone gives you a quest and someone else gives you quite the opposite you can somehow complete both sides, get the full rewards out. Also lieing you did something could be sometimes possible. But there should be a bad thing about that too...
I agree with this. (sorry I always get my examples out of gothic 3, but thats the RPG I played the last)
Again about that slave I talked about, (I believe the second post of this thread)
It should be possible to have the option to say to him: "hey, I'm actually one of the rebels, but I could use the reward, so what if I bring you back to town, claim the reward and then I will free the city (and maybe give you a piece of the pie)"
So basicly you take that slave back to the city for the reward but you free him just moments later. Thats what I wanted to do.
There are however some thoughts that crossed my mind just now.
If the quests are too much the opposite it shouldn't be possible to finish them both. In gothic 3 (again, I know <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />) you could accept the quest to destroy the rebels hide-out and the one to free the town, you could however do both and that is kinda silly. Unless offcourse you hate all living things and want to be the only person in your gameworld in the end.
So I think you should be very carefull on wich quests you allow to be taken on at the same time.
However, taking on opposite quests isn't very good if you want the replay the game but do the opposite of what you did before.
And about the lieing... I don't know if that is a good idea, it would be like I used a cheatcode to finish it. (unless if it fits the story)
