In this talk, one of the most oft-asked question of independent game development will be discussed- should I build my own engine for my game, or use an existing middleware? John Edwards (thatgamecompany -Journey) will represent the opinion of building your own and Alexander Bruce (Demruth-Antichamber) represent the middleware-using perspective. Through prepared statements and a moderated debate, the audience will gain a deeper understand of the pros and cons of each. Come to learn, or have your existing preconceptions challenged!
