Every other game keeps two people from having the exact same name. Two people could have the same first name, or the same last name, but not both.
Here, someone's first name and last name counts separately for this. Here, two people can't have the same first name despite this being common in real life. Here, two people can't have the same last name. DM's call if they aren't related, but married couples are common, and siblings are common! But here? nope.avi.
Me having to resort to the in-game random name generator is an insult, but even that sometimes provides invalid names due to the above.
Dwarves are single-minded creatures that have been known to sit around for hours watching the forge heat up, and true to my Stonehammer heritage I am going to stubbornly wait for this to be fixed before doing anything else.
