@Myrtos: Yes, but in earlier times we just didn't have this stuff of question marks floating over/on the heards of people. I might be wrong, but I think that Blizzard was the first to invent & use this, and then everyone copies it. It has become some kind of "industry standard" since then. (Of course, mini maps are a similar thing, but they don't break the immersion as such for me, because they belong to the HUD, not to the in-game world.
These floating thingies just break the immersion so much for mew, because they look as if they were in-game, but in fact they are "out-game", so to say, and should rather appear in the HUD or anywhere else, but not as if they avtually belong to characters.)
