Checking now, there's one line of dialogue that changes depending on your race.
Where is it? I only see the one in Helgen when you first choose your race.
In Morrowind they had a reputation system with inter-faction relations affecting how people initially treat you. They could incorporate that sort of thing with additional snippets to communicate the reason why someone likes or doesn't like you ("I don't break bread with the Legion", "an Altmer is always welcome at my hearth" etc.)
That could actually be fit into the prejudiced/unprejudiced categories I mentioned with a simple [race] insert. It really wouldn't take much work to implement something like this.
I'd prefer more exclusivity for factions and guilds. I don't think you should be able to side with everyone and get to the top ranks in every single faction. I liked it in Morrowind how you couldn't join more than one House, and your actions in some factions would lock off progress in others (like assassinating crucial people as the Morag Tong etc.)
Eh, well, so long as we're letting the player be a mary-sue with the leveling system beth put in place, (which I'm not necessarily opposed to), there's little reason to cordon off the factions that are in the game.
Could an arch-mage kick ass with the companions?
Similarly, could an assassin or non-pacifist thief be useful or even relied upon?
Is there some doctrine that a fire-breathing barbarian can't be allowed to study in the mages circle, so long as they minimize the barbarianism while on the premises?
But I think we're getting kinda side-tracked here.
Standard armor looks customizable. There's a still of when they're showing off the pip boy edition that shows (in addition to a curved ripper and a triple barreled missile launcher with added bayonet) a character equipped with light combat armor over a vault 111 suit. Some parts of the armor are listed as shaded, others as fiberglass, and I'm pretty sure I recall a third type.
This all kinda looks like the kind of thing you could do with tailor-made in NV. Slots for mix & matching. If it's extended to mix & matching for
individual pieces, now
that would be more impressive.
