A Game By Its Cover is one of the coolest independent game jams going around. It tasks entrants with picking an existing piece of fake video game art - often a cartridge from Meteor's awesome Famicase exhibition - and making an actual game out of it.
This year's edition kicked off in June and closed over the weekend. One of the entrants is Argument Champion, based on the Famicase cart below and pitched as a game in which you detect audience sentiment and use it as a means to beat your opponent in a formal debate.
With a neat "linking" mechanic to string together your arguments and a liberal helping of Mother's art style, it's worth taking a look at.
