I'd like to start developing a board game I love playing. There's an iOS implementation of it, but none for android. I don't even know where to start and which principles I could possibly follow. I've been working as a (business) software dev for the last 20 years, so I have some clue about programming.

I don't want to care too much about the graphics, it's the computer opponents and the game rules I am interested in.

No language constraint ;-)
