Legend
Again, novels, books, movies, other media. Totally different concept.
I don't ask many of the PC's last names in our group much either, but I bet quite a few people know the name "Do'Urden" or at least know it starts with a D and it's weird.
I have never seen a PC's race "never, EVER" referenced. I have seen it not brought up in a single game. Why? Because we all know it. Unless we are interacting with a lot of NPCs and the DM has one that has a special interaction with a given race that is in our group, it's not something that comes up a lot.
Course, I read a post here on the boards about a month back where the player thought that he no longer enjoyed the acting part of roleplaying. He'd just as soon have the DM tell him what he needs to know without all of the flowery roleplaying. Personally, I would be ok with that. In my old age, I like to cut to the chase. I've had my fair share of pedestrian roleplaying over the years (i.e. spent a few hours talking with some NPCs and it led to something that we could have gotten in about 5 minutes of our time) to start to like not just combat to speed up, but roleplaying as well. In such a situation, reiterating for the 120th time in the campaign that Bob's PC is an Elf is just a waste of time. I'd rather be exploring, or telling jokes, or fighting. Something a bit more fun than such repetition.
There's a vast gulf of middle ground here that you're ignoring.
For me, I will literally rewrite my entire campaign world to accommodate someone's character concept. In return for that, I expect the players to actually play the character that's in front of them. It's the expectation at our table. It's no different than a player who chooses to be Lawful Good and then cheats and steals and is totally unreliable. Or a player who dump stats Int and Wis but suddenly becomes a Seal specialist whenever danger happens. Or a player who brings a cleric to the table but cannot be bothered to actually give any thought to things like rituals and beliefs for his religion.
Play the character that's in front of you. That's all that I ask. A player whose portrayal of his character is so lacking that you cannot tell what species the character is needs to up his game a bit at my table. That's all I ask. If it's "reiterating for the 120th time" then it's not much of a portrayal. You should never have to say, "I'm an elf". It should be obvious from what you do at the table. If it's not, then, why are you bothering to play an elf? Is it simply for the stat bonuses? I'm not really interested in playing with that kind of player anymore.
If I'm willing to completely rewrite my campaign world to accommodate a concept, I figure it's a fair trade that I expect a minimum degree of engagement from the player and make his choices actually matter in the game.
