Hello everybody, this is my first post. Some of my ideas...
Huge (optional) training at the beginning of the game. OFP series (OFP and ArmA, not OFP2) is awesome and is one of the most complex game on the market, but unfortunately it doesn't have proper training.
In my opinion, training should contain:
Many hints and tips for military strategies and different approaches to combat
Learning all the keyboard functions and key combination in different situations (please more user-friendly interface)
Shooting with some of the weapons on different targets and driving few vehicles, basics of squad leading
Testing all this in particular situations with guidance - learning on how to be more efficient in combat and more stealthy, how to use terrain, topographic map and compass more efficiently, etc.
