I don't think that was a design flaw, per se. A lot of people don't like it, but that's how they designed the game.
Anyway, they have talked about that (in podcasts and on Twitter) and seem to understand players' feelings on that. So I'd imagine they'll try to work with that in mind.
True, it wasn't a design flaw because Sierra intended it that way, but it was still a dumb ass way to develop games. Well, games used to be infuriatingly difficult back in the day, so fair enough. That's how it was back then. But if they release a game as unforgiving as the original Space Quests today, well, I hope they know better.
Ideally they'll have a "hardcore" and a "casual/normal" mode.
