The computer version of the Avalon Hill board game Empires in Arms looks like my Holy Grail of campaign systems. Since its inception, it has always had the ability to resolve land battles outside of the game (i.e. on the miniatures table) and then input the results of the miniatures battle back into the computer game.
With a recent patch, they have brought this miniatures compatibility to naval battles too. Now, you can choose to fight out your land or sea battles either in game or with miniatures. It looks like the perfect grand strategic campaign system for the Napoleonic wars in miniature.
I'd tried to use the old board game Empires in Arms to conduct a miniatures campaign, but things bogged down because we had to physically keep track of the board, pieces, etc.
I considered using one of the play by e-mail systems for Empires in Arms, but they all seemed a bit clunky, and to make the game work well, you had to find 7 people who wanted to play. This computer version of EIA has an elegant interface, and the computer handles all of the record keeping, calculations, and "paperwork." It is built for play by e-mail, which is terrific.
Also, the computer AI will run the major powers that don't have human players, so all 7 major powers are represented even if you have less than 7 players. (Which is good, because I'm something of a recluse and don't even have 6 friends.)
I'm truly excited about this game. With the new ability to resolve naval combat with miniatures, I am for sure going to get a campaign going. (It always seemed wrong to have a Napoleonic grand campaign with no miniatures naval battles.)
I'm busy now working on translating my favorite Napoleonic miniatures rule sets for use with Empires in Arms. (I've also got a good incentive now to finish painting the Russian artillery I need to put together a viable Russian army.)
