For those not in the know, Three Thing Game is a programming Game Jam run over (approximately) 24 hours. Teams of enthusiasts (that’s you people, as well as me and my ‘kind’) gather to challenge themselves to create a game based on 3 random words that they will be given. At the end of the 24 hours you get to subject your game to a thorough Judging against various criteria like: adherence to the Things, how complete is your game, and how much money you slip the judge discreetly.
Over the years teams from all years of study have made some great stuff, some of which has even been published in various app stores. So you should definitely not be discouraged from taking part in your first year. This is an excellent opportunity to put your skills in to practice, to hone your craft. This is also one of those ‘extra-curricular’ activities that help to distinguish you in the eyes of potential employers from the 300 other people that will be graduating from here at the same time.
