The guys at Autarch have started a Kickstarter for the ACKS Player's Companion. It's already over galway funded with 5 weeks to go. It's pretty safe to say it's going to hit it's goal, and maybe even a bonus goal or three. New classes, new spells and a point based customized class system, that allows you to design your own classes. It's backwards compatible to the classes in the core book and the Player's Companion, so balance should not be an issue (or maybe it will be. stuff like this shouldn't be in the hands of a min/max player, but it's an awesome GM tool)
Here, let me borrow from their Kickstarter page:
Pretty damn cool!
Yep, I'm in again. I like getting signed gaming stuff ;)
