Re: Campaign Skills Package
Does seem like there are too many possibilities for Connections, but just remember that the Event doesn't have to be the actual Connection, just the reason behind it. For example, Vonon might have attended a funeral for a friend, and then tried to drown his sorrow at a bar afterward, and some other character would have met him there. The second character doesn't have to have had anything to do with the funeral.
Also, while the idea of a triple-Connection is interesting, I think in order for it to be balanced, it would only count as a single connection for each of the characters involved, but you'd all have to gain the same skill.
As for the designation format Skill-1, I suspect it harkens back to the early days of the game when memory on computers (such as they were at that time) was very limited, so any opportunity to pare down data was significant.
In any case, there's never actually been a 'thou shalt list thy skills this way' mandate or commandment, so it's whatever works for each player.
