I am planning to buy ArmA2 (since I keep hearing and reading great things about the game!), yet I'd first like to check whether it is possible for players of versions bought in different places (e.g. Steam, D2D, boxed copy) to play together, and also whether there are are any region-based limits to multiplayer games?
The best (cheapest ;)) option for buying for me it to buy it boxed here in Ukraine (it is a legal copy), but I'd like to be able to recommend it to friends and play with them, so I'd appreciate any feedback on this.
Thanks!
