Hey there,
I'm the developer of Battlegrounds Gaming Engine.
I wanted to let you all know that you can currently get a Gamer-8 BGE Client license for just $17 USD, via this Kickstarter campaign, which ends in 4-5 days. This license allows you to host online games and have up to 7 players log in and play using just the free BGE Demo.
The KS campaign itself is for developing token content that most of you won't care about (aside from perhaps the Vietnam era tokens), but I am offering discounts on both BGE and BRPG (my other app, for playing RPGs) to help achieve higher funding than I would otherwise.
I also wanted to mention that BGE is currently having a "free use" promo for the duration of the KS campaign, so if anyone wants to take the program for a test drive and use the app fully unlocked for a while, now's your chance.
There's a video tutorial that walks you through the entire process of porting a game to BGE. The process is really quite simple, and BGE should prove to be an empowering toolkit for those who have had no luck trying to create their own game modules in other virtual tabletop apps.
By the way, to better support tabletop miniature wargames, the next release of BGE (v1.8) will let you move formations of units and wheel/pivot them very easily and with great precision. It is due for release in a week or two.
