Perhaps an alternative is to split into guilds - many of them - and pose an Epic Quest; game moves are contributions to a dialogue (conversation) map which, first, responds to the quest (a deep question) with position/answer statements to be followed by evidence fields the guilds collect to support their position. Other guilds can come in and gain game points by adding support to the game moves of others, or, for that matter, challenging them with evidence to the contrary. Game moves include Questions, as well as answers and pro and con arguments. Thus, this is not a simple Pro-Con ecosystem, but, instead, a conversational one. This, in theory, can be viewed through several lenses, two of which are "debate" and "learning conversation". To the extent that the epic quest is one which, effectively, crowd sources the world views expressed by guilds, and to the extent that rules of engagement mean that the pugnacious arguments remain inside the guilds and what comes out forms valuable contributions to the conversation which is the quest, then "all boats rise". John Seely Brown did a 6 minute Youtube with the opening sentence: "I would rather hire a high-level World of Warcraft player than an MBA from Harvard", and that point is evidence to support the model I'm suggesting here, something like "World of Warcraft meets Global Sensemaking". JSB's point is that guilds perform magic on humans; less tendency to argue, more tendency to find ways to remain on truth seeking missions rather than "selling" personal versions of truth.
