You could try pokemon sapphire, ruby, or emerald, I don't know if it will really be as good as LeafGreen, (I liked fire red better) But you might like it better! :) And if your gameboy has somewheres to put Gameboy games try pokemon crystal and yellow, those are pretty classic and good games :) Good luck!
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.
