Heh... funny thing is that even though I tend to really like to "cloth" my characters in heavy armour... I still tend to like to sneak around everywhere, with my heavy armour on. XD
I like to sneack around, try to figure out how many opponents there are, where they are, if they have any walking pattern they do, and if so where do they go and do I get some kind of opening to do things due to it, or will I be able to take that guy out without the others noticing. And then based on that I will try to make a rough plan of what I want to do, where to go, who to take out (be it knocking unconscious or killing, depends on the game and if you can knock people unconscious or not), and where exacly to take them out.
Sometimes the plan just ends up being loads of miniplans for each individual opponent, where I take them out one by one at the opertune moments,. But other times it is all one big plan where I will wait for the right moment and then go on a long string of taking the opponents out one by one quietly, without much or any time wasted. Then other times my plans change at some point due to something unforseen, at which point I pull back and reassess the situation, or it turns into a ball to the walls allout brawl and/or gunfight untill the opponents are all dead (or possibly sleeping). Occationally I can tend to be a bit impulsive, and dive right in, but those occations are rare.
I rather spend 10-30+ minuts doing all this... then rush in head first shooting up the place and be done in 3 minuts. The end result is virtually the same, and takes less time if I did it that way... I just can't bring my self to do it the run-and-gun way if I am able to do it the way I like to do it. Essentially I should probably be playing more rogue and/or ranger types of characters... since they tend to be more suited for this kind of a thing... I just like using the kinds of weapons and armour no matter how I tend to play.
In general this is how I do things when I play games by my self though. When I play with others (videogames seldomly or never... with pen and paper rpgs, board games, table top games, that I play with others, is different... there I will have to speed everythig up a little... but I still do for example spend time asking the GM "How many are they? Where are they? Weapons? Things I can use to my advantage?" and a few other things like that... I just don't spend half an hour on it XD ).
In Shadowrun Returns, and the following expansions/updates, you could not really play it this way as easy. There if I saw a fight coming I just tried to make sure my guys where in a somewhat advantagious possition so as to them being in cover or close to cover befor the fights started.
