Both devs may have pulled from the same reference? I find it had to believe that Bethesda would rip off of someone else.. lol
Of course Bethesda wouldn't use other people's ideas, that's just inconcievable. After all, elves, orcs, dragons, goblins, werewolves, undead, and all those things are all original creations of Bethesda, no one else has ever done them before.
But that's an interesting find, however, it may not be that Bethesda intentionally drew from Wizardry, looking at the image of the symbols from Wizardry and the dragon writing in Skyrim, I can't really make out any that seem to be identicle, very similar, yes, but not quite identical, and that could be a result of both drawing from the same sources, and to be perfectly fair, neither of the scripts are really extremely complex, so it could be very easy for similarities to occur between them, even if not intentionally. Now, it's possible that Bethesda could have drawn from Wizardry, yes, as my sarcastic sentence earlier in this post indicates, Bethesda has borrowed ideas from other sources before, and maybe they're doing that here too, I'm just pointing out that just because there's similarities doesn't make them intentional.
