Gregor Hutton was giving a demo game of one his 3:16 variants: Carnage amongst the Tribes. There are two versions of the game planned, AD316 based on Roman Legionaries and slightly more historically accurate and the Tribes game that is medium fantasy in a Conan the Barbarian style. The game is a refinement of the 3:16 system, the biggest change I noticed is that the between combat scenes have been completely reworked. You now have a set list of scene types you can play out between combat and each one has a mechanical effect (unless you are deliberately going for colour only, which would be unlikely) on the upcoming combat round.
The background of the game is that you play the elite warriors of a tribe whose totem god has tasked them with attacking another tribe. Warriors can gain the favour of their totem by killing more of the other tribe than their peers.
Combat is essentially the same as 3:16 and all the usual tricks and tactics seem to work in this version too. What really is very different is all the roleplaying flavour around the game. You get to build a tribe together and determine where the tribe lives, their totem and their cultural and magic keywords.
As warriors advance in favour the non-favoured members of the tribe get to decide what strictures and taboos apply to the rank their fellows have risen to so you get to evolve the tribe as well.
Rather than 3:16’s alienation amongst the stars there is now a rather more individual path for the game which has more player input.
Both games seem to be significant improvements on the original system while retaining all the good stuff about 3:16. Personally I am glad of the changes as I felt that 3:16 was an amusing change of pace but too slight to really call itself a roleplaying game.
