Essentially, we were just playing a loose forum version of the team-betting games folks play all over the world during major sporting events; a god was assigned to represent each team, and then the forum-goers tried to guess which gods would win through an entertaining mix of the god's capabilities in myth, the soccer team's capabilities this year in their games, and who they thought would end up matched against whom in both categories. Totally coincidentally, we saw a way higher percentage of more obscure (to a lot of us around here, anyway) deities being chosen than usual, because they just so happened to be representing teams who were favorites to win.
At any rate, it was just a fun forum game, one that John enjoys running now and then. (He also does it for March Madness' basketball tournament, and you guys could probably bother him into starting it up for other major tournaments if you put your minds to it.) When we were setting it up, though, for fun, we decided to have each team be represented by a god from the same country they hailed from; it gave it a neat extra layer of connection between team and game, and, thanks to the prevalence of Central and South American teams in the World Cup and the general lack of scholarship on mythology from those areas of the world, got to showcase some deities who otherwise don't get a lot of face time.
There were a lot of them, so I won't go super in-depth, but here are the gods who "competed" this year (in order of what place they finished, for extra sports seriousness!):
32. Hunahpu and Xbalanque (Honduras)
31. Mwenembago (Cameroon)
30. Susanoo (Japan)
29. Chachongbi (South Korea)
28. Waang (Australia)
Ogun (Cote d'Ivoire)
Jarilo (Bosnia & Herzegovina)
Edit: Holy cow, we totally swung and missed on this one! We accidentally misidentified the Juruna and their jaguar god Sinaa as Uruguayan, when in fact they hail from northern Brazil. We apologize for the error, and solemnly swear to make sure we copy-edit our posts better in the future.
Gurzil is a little-known solar bull god of the Imazighen people of northern Africa, including Algeria, who was a powerful patron of warfare and whose icon was often taken into battle by various rulers to ensure their victory. He had foreknowledge of events that allowed him to spoil enemy battle tactics and pass on crucial information to his followers, and because he was believed to symbolically reside inside his cult statue, he was "stolen" and "reclaimed" multiple times over the course of various wars and skirmishes. A god who can spoil your opponents' strategy and guarantee your victory - not bad for your football prospects, right?
Nanabozho (United States)
La Cigua (Costa Rica)
As you can see, even with super quick un-detailed versions, this still got ridiculously long really quickly (what is it with me and long posts lately?). We actually really enjoyed getting to assign some gods that might not be as common knowledge for the forum game; since countries that don't often get the anthropological spotlight were at the forefront in the World Cup, it was the perfect opportunity to show them off!
