With most of games virtual now, I'm thinking of reviving my much beloved Unkerlant campaign. It's a early 18th century Imagi-Nations campaign full of political plots and skullduggery, with battles fought on the tabletop. I would pick off where we left, but unfortunately one of the original participants is no longer with us.
I did a ton of backstory. The world of Unkerlant has a lot of depth. It would suit well with remote games, and might be especially fun doing online with Newsreel type updates and newspaper articles.
We started more than a decade ago, so if you missed its old iteration, check it out here.
