But in general, it greatly depends on the method of data transfer; the "lightest" is connecting via IP (only for those whose external IP can be accessed).
Then there are emulators like Hamachi, PLan, and GameSpy.
Hamachi, as practice shows, increases traffic by 30%.
As for the others, I don't know – I haven't conducted experiments.
I repeat: on average, one game through Hamachi consumes 5-10 megabytes of traffic. If this information doesn't seem comprehensive enough to you, test it yourself.
Но поскольку я нищий,
у меня лишь есть мечты.
Я разостлал свои мечты пред вашими ногами.
Ступайте бережно, ибо вы ступаете по моим мечтам.
