You actually care about something like that? I mean, Morrowind already had vaguely Mesopotamian Hlaalu buildings and Redoran shell huts next to European-style Imperial houses and dwarven steampunk ruins and Lovecraftian daedric ruins and Telvanni mushroom towers. Mixing cultural influences from several different continents and millenia into new chimeric fantasy settings seems to be what Bethesda can do well.
Why should the dragon language fit the nordic setting, anyway? Dragons come from Akavir. If anything, they should be writing Chinese.
The thing is, Morrowind with its cultural clashes was basically a fantasy version of the middle east, and all of the real-world references fell roughly into that region, so it all kind of vaguely fit together. A lot of the backstory was precisely about the mishmash of influences and the dunmer hating the imperials for imposing their culture on the province (the parallel made all the mode blatant by the Imperials being Roman-styled). There was a
reason for it. The cuneiform just seems... random. Like they thought: "Well we need a new script, but we don't want runes, that's too obvious, so let's pick some other distinctive looking script from the pages of history."
But maybe I'm pre-judging. The only piece of info so far is what the script will look like, so maybe this new piece of lore will be exceptionally well developed and interesting. After all, I did hate Morrowind for its weirdness for the first couple dozen hours or so, so maybe it'll grow on me.
Also, I snickered at the "chimeric" reference there. Exceptionally well punned, sir.
