I used Open Office to write my last two books and a handful of novellas. It's very like Word 2003. I did have a few hitches using comments and doing corrections the editors marked (going to the next one skipped two, although I did see every one, just not in order), but the most recent version seems to have un-glitched those features.
Like any word processing software, learning how to use its features is vital. And you absolutely have to back up you work, every time.
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.
