Plans after I publish Appocalypse

After I publish Appocalypse I plan to make a video game for it since I want to be a video game designer. Then I will write the 2nd book in the series, if there is one. Once again I do not know how many books will be in the series or if there will be a series. It might end up being a single book. I am hoping to make it a series of 4 or 5 books but I am unsure of the number for now. If I make enough money from e-reader versions, which will come first, I will print physical copies that readers like me will like. I don't really like e-readers but I do like physical books because I can smell the book smell and I can feel the pages.
