Sounds like lazy students to me. I mean, yeah, just try to jump straight in, that's fine, it's understandable, most games - even old ones - were designed that way. But when you're totally baffled, and someone has basically given you the equivalent of a strategy guide with it LABELLED as the game manual, wouldn't you bother to look in it? I mean, it's not even a heavy book, it's just clickety click, and rub your scroll wheel to move between pages. Ctrl-F, Controls, Enter will get you the basic knowledge.
Never mind Ultima, I've got a few games from my own formative gaming years (around 90-95) I'd like to try them on. See how far they get in a combat flight sim like F19, figure out why their randomly-flailed Simm'ed City is dying on its arse, or how come everything in MegaLoMania* takes such a damn long time. Stuff like that.
(* ok, that's officially going to have to be dropped from my Old Game Example Reference List for at least a week now, it's getting over-mentioned)
But it's the way of the internet generation. In a time when an unimaginable ocean of informative, largely text based information that could tell them anything they could ever need to know about how to do something, why something happened, etc, they'd rather watch a few youtube videos, go on yahoo answers and ask the same stupid question that's been asked 100 times before and could be answered with a quick site-search (and read) or google, then complain "tl;dr" if someone dares write a response longer than three or four lines.
It's infuriating, and inexplicable, but hey ... it's going to be their world eventually. Let them figure it out. Maybe they'll mature into it.
FWIW Ultima probably would have bored my pants off as well. As games go, it is pretty longwinded, slow and contemplative, with little payoff in excitement, music or graphics... there's just not enough time, unless you were immortal and it was the last thing left to do in the world. A full on round of Railroad Tycoon or Civ is stretching it, and I've learnt to avoid Gran Turismo because it manages to bypass the temporal-awareness parts of the brain. Never got past the second level of Dungeon Master. Too much investment required.
(Same reason I'm probably not going to buy Minecraft, or a DS of any type, even though I *KNOW* I would love both of them. Free time - currently spent not only on this kind of nonsense but constructive things too - would vanish)
