Which alternate history would you like to know, what really would happen?

[Compsognathus]

Let's say, that you if you had the possibility not only to know exactly, what would happen, and what would be the world like today, but also enjoy some things, for example books, movies, newspaper, or anything else, or meet people from the alternate universe to know even more about it, what alternate history would you like to explore? No matter, that it is impossible.

My top choice would be, if Germany won WW1 in 1918, then I would also like to know, what if Germany restored monarchy in 1930s, and did not start WW2, and what if Nationalist China won Chinese Civil war. And as a Czech, I have to say, that scenario, what if Czechoslovakia had fought in 1938 would I also like to know, what would happen.

I'd be curious to see what the world would look like if Hannibal had sacked Rome, instead of inexplicably turning around after crossing the Alps.
