Game Theory is a field shared by math and economics that aims to describe strategies and outcomes of games. A game is simply a set of possible decisions and their outcomes. While Game Theory is immediately applicable to certain board games (Tic-Tac-Toe and Chess among others), its usefulness goes far beyond into areas such as public policy and business strategy.
Developing a game intended for multiple end platforms can present some unique challenges to consider. For one, the differing pixel resolutions on apple devices over the years necessitate at least some different background images and layouts to accommodate the different aspect ratios. My initial technique to deal with this problem was to include a copy of each background for each device present in its scene, with its rendering switched off.
