Oh I am totally going the stealth route, always have in games... even in games where "stealth" per say is not even something that actually effects the gameplay at all, because there is no real mechanics for it or something. I even use stealth in games where it's not really that effective based on equipment etc... like in Skyrim, most of my characters have been guys in heavy armour, and yet I sneak basicly everywhere anyway.
Sneaking around and figuring out where all enemies are, where to best hit them so noone else notices it, find all the possible entrences to a place, etc, is my thing. And then either go in and do it silently at close range, or silently at long range, depending on the current situation. And if I where to be noticed at some point how I react would depend on the game.
In games where it is possible to get back into hiding and eventually the enemies calm down, I will move away, hide, and wait, and then reassess the situation, and get back to work. In games where once your noticed all enemies instantly know where you are, and you can not get back into hiding untill all enemies are gone, then I try to find a possition where they can only come at me from one direction so that I can pick them off one by one befor they reach me.
I love this style of gameplay, it fits me a lot. I rather spend 30+ minutes doing it this way, then run and gun by way in and be done in less then 3. EVEN IF I do not get any kind of "reward" in the game for doing it silently and unoticed. I do it despite the kind of game it is, and/or despite any actual kind of reward you might or might not get, and/or other reasons.
As for autoaim...
If the game ends up being that it is my own skill with FPS gaming that is the guiding facor to how good I will be at hitting the opponents, then I DO NOT want any kind of autoaiming. I do not mind if that kind of autoaiming is in the game, as long as I can turn it off compleatly.
If the game however have full stat's based accuracy and hit chance, then I do not mind if there is "autoaim" i the game that increases the characters chance to hit. Of course it must not be to powerful, I would not want Autoaim to be so powerful that a character, who is not combat oriented, becomes almost as good as a combat oriented character.
