It is representative of it being a different thing. That's what rules are for: to represent things in the world.The only current difference in mechanics is how long it lasts, correct? And elves still have to rest for 8 hours, just not sleep. I don't see how that is measurably different from a mechanical perspective.
Okay, Grod.Awakened gorilla. Final answer.
Only correct answer.
Whatever the "this" is that elven culture has is going to arise in mechanics at some point. In this case it might be when an Elf accesses memories from a previous lifetime; even though there's no roll, being able to access ancient memories without having to do historical research etc. is still a mechanical advantage Elves get that other species do not.I think you know my position all this, but not necessarily. They could just be fluff, lore with no crunch, just a 'oh elven culture has this because they can access their memories from their various lifetimes' or whatever.
No mechanical benefit, no extra rules, just a claim in the lore that does nothing.
Hypothetical sitation: you are joining a new campaign in which all other factors are positive (you know the GM and group, it's in a setting you like, whatever) but there is one hitch: race/heritage/species is cosmetic only.
I mean, I stipulated that everything else was positive to you, so it's up to you what edition and world you are answering from.
The mechanical advantage to long life is they get to use their living memories to access historical information where Humans have to go digging through old books and scrolls (which takes much longer) to access the same stuff.First off, I don't think long life qualifies as a mechanic, unless the game in question has real and impactful aging effects. They were real in some TSR era D&D, but never in my experience what one would call "impactful." I guess maybe elves and dwarves could handle a lot more haste spells cast on them?
Depends. Does the trance take less time than normal sleep? Is it easier to awaken an Elf from trance than a Human from sleep? And does that sifting of memories give any advantages when recalling ancient information?Or to use your elf example: elves experience a trance rather than real sleep, and their dreams are not dreams but the sifting of memories of many lifetimes. You are absolutely right that should inform both individual elf characters as well as elf culture broadly, but it does not require any special game mechanics.
Let's go even more basic. I'm a human scout. I see a Goliath fighter. I ask the DM to try an assess what kind of a threat he his. The DM says he apears to be about average build for a Goliath. What the heck does that mean? Should I expect him to be stronger than a human, using larger, more dangerous weapons? Because Goliaths are obviously stronger than humans and use big weapons that do more damage. Or does average build for a Goliath mean he's the same as an average human?
Honestly, this just sounds like a mess. Easier to say "Everyone is a <insert race here>" than to say "It's cosmetic only". I can get behind the former. The latter would take a lot of work. And if the DM doesn't have an immediate answer worked out for the questions, well, that's a sign the DM really didn't know what they were doing.
