I've had a lot of fun DMing for my friends with [url=https://img.4plebs.org/boards/tg/image/1366/05/1366053319764.pdf]Stars Without Number[/url], but since we only get to play once every couple of weeks, I figured I'd try out a campaign here. 
If people are interested, I can give some more explanation and post some more resources, but the quick overview is that the group will operate in a semi-sandbox environment, and will unlock ancient secrets as you travel through space on a player-driven adventure. The campaign would start at first level, and hopefully last for quite a while.
Additionally, I think I'm going to try out [url=http://invisiblecastle.com/roller/]Invisible Castle[/url] for dice rolling, since it lets everyone roll their own checks but keeps them accountable. 
If you have any questions feel free to ask.
