There are scenarios written as well as battle generators and a campaign is currently being worked on. Over 200-unique designs have been created for the era from 1895 or so through to about 1907 for Britain, France, Germany, the United States, Italy, Austria Hungary and Turkey in addition to Russia and Japan all getting pretty complete treatment. There are a lot of hours being put into this but responding to Player submitted SAI issues does absorb time otherwise available for the RJW.
Some screenshots from test runs:

Here are the Track Charts from a test campaign scenario as the Japanese Player. The Russian AI sent a cruiser force from Vladivostok to the Tsugaru Straits, sinking a couple of merchants and the Japanese were never able to catch them.
