Zanzibar. I never wrote i want to aim with mouse ;P What i wrote is as long as your manually skills in using keyboard/mouse don't come into play then it is good i suppose. Although we still move with keys/mouse so the berder which should which shouldnt isnt so clear.
I can fully agree with the choise which you have gave as example but each of these theree options can still have suboptions, like some player influence on aiming, but repeating myself: as long as your manual skills don't come into play (We need some more or less clear border along which we build ideas, common sense doesnt always work and i'm not speaking about anyone in particular)
Wow, this post is becoming semi-long.
As another example where manual skills doesnt really count and where you use your brain:
Exploring. Your char don't actually remember the way through some kind of skills/artificial memory. You do. if you forget, your character has to forget too if you don't want your character to lie when he will be actually asket for the way.
We could have maps as some kind of char memory. Furher, we could have window with places and just click to move there (fully automatically, if you get lost skill dependent and so on). But we don't have this system. We don't have maps. It has been said very clear. Why? thy avoid this apportunity to decrease player factor?
I think, first of all, because it is not fun. Second, because it is not good to decrease the player factor too much, because we spoil roleplaying by decreasing apportunities to it. It would be much more time consiming to code it to the point where you still loose marginal opportunities, but a lot less. You loose also realisim which also influent RP.
Look at current way how you fix weapon. Simple system and players found loads of possibilities to use it. Devs could spent the same amount of time developing repairing at NPC. but you wouldnt lend item. You wouldnt talk with NPC while the repairing process (They are dump ;P) The player based economy wich is IMHO good would suffer.
We need rather clear border, which will tell us which actions can be player dependent and how far.
I gave mine. Whats yours planeshifters?

(hah! good old term

) Give some reasons and examples if you want your idea to have any weight ;P (A problem of many people in this community, but still beter than in some other game communities )
