First player I met when started playing FOnline 2238 was Russian (i discovered it later). As I just registered my 1st character I was excited, because I've never ever thought there will be fallout online, so when I saw him I said "Ooh! Alive human!". He was in metal armor with some rifle in hands, it was Den, January 2010. There were some other guys, and it seemed they wanted to kill him. So I talked to him and said that I'm new here and just registered, he said that it's nice etc. and said if I need help. Then he said that he will give me pistol and ammo and went somewhere, I was standing there and waiting. One of other guys (who were Russian too) went from house with bazooka and asked me where did he go, I answered that I don't know. Then 1st guy returned and give me desert eagle and some .44 ammo which I'll lose on my 1st encounter later vs raiders.
So I was freely walking Den full of "evil Russians", and no one killed me. Beginner's luck?
Btw if a lot Mongolians were playing FOnline, you would make thread "What the deal with mongolians?" Just because most players are PL and RUS, obviously most PKs will be PL and RUS.
