Hi Bobokil, thanks for the reply.
(2) Yeah, good point about taking into consideration the owner of the territorry.
True, if for example, you attack his bunker, and you decide that you need to retreat, he can catch you up, but he will need to move outside of his bunker for that. So not every situation in enemy territorry is hopeless. Also, enemy player must actually issue order to move his armies to chase you, which will not happen always.
(3) Sorry i don't quite understand this :-/
(4) Yeah, but you can't always look from the point of view of good players. New players also must be given a chance to play this game, and to correct their mistakes. Otherwise, new players will just say "stupid game" and quit. It's important to attract new players. Most of my games that i play is already a graveyard of inactive players...
