I'm a big fan of Battlestar Galactica, but have an issue with games with an even number of players. For these games, the game recommends replacing a Cylon with a Sympathiser to help balance it.
For the unfamiliar, at the half-way point, the Sympathiser basically becomes a (weaker) Cylon if the humans are "winning" (i.e. all stats are above half-full) or remains a human (but is brigged) if the Cylons are winning (i.e. when any stat is below half-full). This helps to balance the game since having an extra full-privilege Cylon would be really tough on the humans, but having a human makes it a bit of a cake-walk.
It's not a bad mechanic, but in games my group plays with a Sympathiser, I find there's a lot of meta-think and the humans intentionally allow one stat to drop (normally one that's not too tough to raise or keep steady like Morale) to ensure that the Sympathiser is on their side.
Has anyone faced (and hopefully overcome) this issue before? Does anyone know of a good house-rule alternative to the Sympathiser?
I've been tempted to use a full Cylon but use some method to make things a little easier for the humans (e.g. have the second loyalty distribution come a little later, or ensure that at least one Cylon card has to wait until the halfway point), but I'd love to hear others' solutions.
