VBS1 is an infantry training tool, meant for use by government agencies and civil services. It is NOT a game,
has no campaign and even the number of single player missions that come with it are few and limited.
VBS1 is nothing more than the game Operation Flashpoint: Resistance, with a handfull of extra scripting commands, that allow saving data for after action review. If you think it looks better than OFP, think again. The graphical engine is simply 100% the same. The only difference is the soldier model, which has a bit more detail. All features look very much like the ECP mod, nothing more.
If you want OFP with the same (or better) detail as VBS1, and even more features, here is what you can do:
1) Install OFP Resistance
2) Install a feature-enhancement mod (for example ECP, EECP, FDF or y2k4)
3) Install and use the new International Infantry model v2.0*
4) Install Your favorite add-ons
Optionally, you can also install Kegetys' Direct3D DLL.
*IntInf II is made by the Lowlands Warrior team, and should be available by the end of April 2005 from http://llw.the-dropzone.net
Believe it or not, but by doing this you will surpass VBS1 from a gaming perspective!
So why is th military using VBS1?
1) It has an AAR (after action review) option (you can use a VCR if you want to do this)
2) It has an observer module for the insctructor
3) BIA developers offer customization a a service
4) The Operation Flashpoint license prohibits the use for professional purposes.
In short:
The military is NOT ALLOWED to use OFP and simply requires extra attention, because soldiers usually don't want to bother expirimenting as they have a job to do.
So consider yourself lucky, and fire up your OFP game!
