I am not going to publish a battle report until the game is over (unless I lose, of course), but I thought it might be helpful to describe how we are conducting the game virtually.
Computer-Aided Tabletop Gaming
Tabletop Simulator: There are a number of games played using TTS, including miniatures games. The most popular I know of are probably Warhammer 40K and Star Wars Legion. Unless you can leverage someone else's work, you need to create a lot of digital assets to represent your troops and terrain. One advantage, however, is that you can virtually flip the table, scattering the miniatures. Of course, I would not need that feature ...
Vassal: As with TTS, and really with all of these choices, you will need to create digital assets for troops and terrain. Lots of other modules exist out there, so you could easier use one of those and raid their assets. The programming aspect of it is a bit tricky, but I have done it before. Vassal provides great logging features, allowing you to replay the game in its entirety, including the die rolls (proof that you were robbed by the dice). I have played a number of board game tournaments using Vassal, but most of the modules for miniatures games with free-form movement were rather clunky.
Roll20: As it so happens, I started a Roll20 version of TSIA and it was not too bad of a development tool.
Given that its root are to support playing role-playing games virtually, supporting things like unit having hit points (as OHW has) is rather natural. Roll20 can have quite a bit of complexity, such as using line of sight and having fog of war features, so if your game has those elements, Roll20 might be right up your alley.
Battle Chronicler: I looked at this tool back in 2010 and used it for a DBA game and my notes say it had a sharp learning curve. At the time Steve-the-Wargamer was using it (not sure if you still are Steve), but Shaun Travers was not keen on it. So that is out, given that Shaun is my opponent for this game!
Ironically, I mentioned Macromedia Fireworks in that post, and how handy I was with it. Unfortunately, that tool was sold to Adobe and it now out of my price range for what I used it for. I have yet to find a cheap or free tool that did as well what Fireworks did. [sigh] That said, I will tell you what I use.
Universal Battle 2: This tool looks to be much easier when it comes to digital assets provided. But it also comes with a "Pro" subscription with a monthly fee. Its main user base appears to be players of Kings of War. If I played that online, I would probably use it. But I could not find a way to upload my own digital assets, nor any information on what formats it supports and so on. From a player perspective though, this looks good.
As it stands though, all of them require up front work and I want to game now.
