Doing a wiki is a lot of work, no matter what methods you use to compile the data. Spreadsheets are harder to read but easier to do and can condense a lot of info in a small space.

There's no reason a Dominions Wiki couldn't be as comprehensive as for example The Witcher Wiki (most of which was made by a single person), but it would take a lot of time. This sort of things usually take the path of least resistance unless there is sufficient motivation and stubbornness involved.
