You mean "Bundesliga", that's the fedearl soccer league. Yes, that's DEFINTELY the most important league, and then comes the second and third league, down to the fourth league, the regional league. Football (the European style, which Americans call soccer) is THE national sport among young people in Germany, and every young person is interested in how "his" team did in the League.
(With a few exceptions, like me.) I don't know what "Esports" is; if you mean "Eurosports", that's a channel on satellite pay-TV where you can watch all the European leagues sometimes on a live broadcast; "E-sports", however, can also mean "electronic sports", where people broadcast live and for free their video game tournaments on the internet.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
