I thought I should mention that in World of Warcraft, grey mobs will still attack you if you get close enough.
Also, in Oblivion I found the easiest way to kill things is to be a stealth archer. Sometimes after shooting something in the head, they will start to move towards my location and then suddenly stop, because I was in such a dark area that they couldn't see me at all.
Oh hey, and I just got done trying to play Mr Robot on Gametap. That game has some serious problems. Tile-based block puzzles with analog movement, instant death tiles, an extra lives system, save points, plus an RPG minigame for hacking stuff. If you go into a room with a bunch of drones and hack them all, then die 3 times by barely grazing the instadeath tiles, you just lost all that time you spent grinding because you couldn't leave the room out of its FUCKING OPEN DOOR to save at the checkpoint next door!
