Huh? This is a great non-invasive HUD. It plays with the art of the game, but is super clean and not hideously colorful. Wish Dragon Age: Inquisition would fix theirs too.
What's a good HUD to you?
I guess Skyrim's HUD is fine if all you care about is aesthetics. To me, it is no good because, for example, you need to trawl through the megamenu to get to the status tab to figure out what is affecting you - that information should be readily available. There are other problems, but it's been a while since I've played Skyrim and I can't think of them offhand. (I'm still waiting for the illusive Dragonborn 75% off sale before diving in yet again.)
Skyrim certainly
can have good HUDs, but that's thanks to mods, not Bethesda itself.
A good HUD needs to present all necessary information in an easy-to-use and precise manner. A shining example would be Civilization 5, which has everything you need to know present in the HUD at all times, as well as an added mode to increase the clarity of all the information that's being presented. Most importantly, the HUD informs you of everything as it happens, and even goes so far as to remind you if you're forgetting something. It does all of this while keeping ease-of-use at the forefront of its design, which is what I find the most impressive thing of all. Civ5's menu style has set the standard for 4X UI (in general) since it released.
SoM's HUD is overfull and busy, but at least (so far) it is presenting everything you need to know. There will probably be niggles about it that I realise after playing it, but right now there's not much to complain about.
