This is sort of like the 'which spelling' game except instead of the same name spelled multiple ways, it's similar names that you choose one of (i.e., Vivienne or Viviette, Theodora or Theodosia, etc). Either gender (though it seems that variations are more common among girls). Basically you say which one you prefer from the previous poster's question then ask your own.
I'll start.
Ashley or Ashlyn?
