would allow for more connectivity between notes
Databases don't have an upper limit of connections.
I'm sure both work fine, but this thing's database-first, as it's meant to deal with queries like 'Events in Belgrade, between 1200 and 1450', or 'random male name from Catalan in 1520'.

Those are both manual tagging. One uses
tag: sultan, the other uses[[sultan]].And you can word-search both of them for Sultan.
Of course, if you have use for a WoD wiki, feel free to convert it. I assume Logseq will let people collaborate just as well with
git.
