If there is a map it MUST be rolled not folded. Whats the point in putting effort into a nice map only to put creases through it.
All the other suggestions have been good, any of them would be awsome. The DVD bonus that would show the offices, daily live of bis, making of ArmA, resaerch trips where they got to play with cool stuff, and definatly a preview for game 2. Of course I would greatly appreaticate that these things also be included in a USA special edition.
