Hi Viktor!
It's very pleasant to hear such good news from Hungary.
In Ukraine we have some sets of rules, which in basic are similar. Main difference is BB velocity. In some rules there are no BB velocity limits(but all airsoft players are feeling the limit), but there is minimal safe distance. 140 meters per second at CQB is very bad.
Sometimes rules depends on people who hold the game. If you attend the game - you agree the rules of man in charge.
No politics in games. Do not provoke police or military. In our country we nave no laws restricting airsoft. Do not wear tactical gear in cities or elsewhere. AEGs must be in cases while transporting.
Game slyles are different: regular games, MILSIM, weekend training, STALKER universe, private games, pistol battles. Some games are commercial. In some games players pay only for game stuff.
Main problem between our markets are customs. Our customs officers are believing that every package contents some bribe because it is similar to real weapon or ammunition. But regular postal service is awful but you can send some staff with "Gift" note. It's no joke - it's our reality.
