As I searched for a video of Silvador (BI tree generator program), I stumbled across the youtube channel of Bohemia Interactive.. DAMN! they are doing awesome stuff!
For example, check this one out, and be sure to note the similarities between the ArmA franchise and VBS (basically the same engine, so all maps and models could be converted with some config tweaks!)
Just check out some more videos of VBS, all technology we might see in future arma versions, too!
BI Youtube videos.
PS: Note the difference between Bohemia Interactive Simulations and Bohemia Interactive (Studios)!
Where the Simulation company(-part) makes simulation programs (not games) for real life miltaries and civilian organizations.
