Advice needed: requirements for building in mobile

Hi all. I'm new to this group and really like the vibe. A few years ago I started working on a project to build a mobile based MMO, basically letting people play cops and robbers using GPS enabled devices but with character dev, leveling and questing like you'd find in something like WoW. I was the plot and (amateur) UX guy, and I teamed up with a group of coders to build a beta in return for equity. We had a great concept and a good sized group of people who were really excited about seeing the product launch and playing the game. The coding company I teamed up with required $ to code, however, and after a kickstarter campaign that didn't make it, we parted ways. I'm really disappointed that I wasn't able to deliver the product to the people that wanted to use it. So here's where I am now.

If I had known how to program myself, I wouldn't have had to rely on a team to build the product. I've come to the conclusion that if I really want to innovate in this field I'd better damn well know how to code. I'd like your opinions on the best preparation for someone who wants to build front and back end in mobile. I am considering doing a CS post bacc BS degree, but I know there are other ways to learn as well. My background and education are in marketing and international relations, so this will be new territory for me, but I'm excited to dive in. Anyway, what do you guys think? Do a 2 year BS in CS from Oregon State, learn to code with something like Codecademy, or something else? Thanks in advance for your feedback.
