vassalA new version 3.1.0 of this software for person-to-person board games over the internet is available for free download. This update fixes a number of bugs, but also improves zooming, installation, and room management, and adds an Aide de Camp module importer.

For those not already familiar with the application, VASSAL is used mostly for war games, but it is by no means restricted to that genre. VASSAL excels at live over-the-internet play, however, it can also be used for ansynchronous situations (aka, PBEM). Playing a specific game requires the appropriate module. Hundreds are available.
