Finding a game topic....

Today I went through my book to find some topics that I would like to make a game out of... I chose to do changes from 1945 to present... It's going to be suprising to see how the world has changed. We have to accept the things that we can't change. It's always interesting to see what people used to do back in the day....I'm very interested in this, I can't wait to see what happens in my game.
