Fodel, who the hell are you and why is your avatar so disturbing?
I am a prick :D and my avatar is a vlish, the most beautiful creature of Geneforge. :D
From the Infinity Engine system for example? You are invisible until you are visible. That's it. The sneak attack multiplier is nothing new either. So? What's so awesome about it and why it's better than the Bloodlines system?
In IE games armor, light, sound is irrelevant (i think ), Bloodlines system is excelent also, but armor is out (i think ) and in Oblivion dungeons are darkness :D
So, you are saying that expecting an awareness slider is way too much?
No, im saying that is not fair compare combat system of a Total War (tactical game) with combat system of Europa Universalis 2 (strategy game), also
but the only indicator that player sees is the eye icon, which has only two states: "visible" and "hidden",
is wrong, you can listen the npc, you can see if npc is searching you, you can decide if the the light/shadow is ok or no, and last you have the icon-indicator, nothing wrong with a awareness slider if you want it, but with or without slider you never know 100% your possibilities of sneak, this is a crpg.
Here is an analogy for you. Imagine a system where in combat you either instantly kill your opponent or die. Why? Well, because you don't know the skills of your opponent. Sounds like fun?
Other analogy, you see a foe, and the game indicate with a green/red icon your possibilities of kill him. Sound like fun? imHo no
Now, if only fighters could sell looted items to other fighters only, the game would have been perfect.
Thieves can loot items also.
