What ? No option for tielfling drow lesbian boink bunny Chosen paladin of Eilistraee ?
Right now, I've played (in D&D) 2 gnomes, 3 humans, 1 half-orc, 1 halfling... I envision playing a dwarf next time.
I'm somewhat surprised people could want to always restrict themselves to only one race. However, I'm not surprised to see that these particular people are either into humans (the "I can't play something that different" syndrom) or elves.
I'm also surprised Angcuru really expects to play a character so long that the lifespan difference between an elf (around 550 years) and a halfling (around 250 years) show up.
If there is any race that you can't play as a dynasty, it's elves. Humans are much more appropriate for this, as you have a real reason to play the new character when you fast forward 30 years in a campaign. Beside, it's easier to flesh out the three previous generations and what they've made than it is for elves.
