Well Grudge. I always hated LG. It was never my style.
But point well made. You'll live with those moves in other games. And frankly, I've watched your comments in NaV with great intent. Fine work my friend. Kudos to you for playing it out. That was a gruesome game. I couldn't do it.
Not all NAPs need to be 'end with N turns warning' either. I often prefer sunset provision NAPs, since their expiration doesn't necessarily mean an imminent attack, and I don't have to announce my intentions or lack thereof.
(ie, a NAP that automatically expires at the start of turn K).
This can let you 'guarantee' peace with one nation for a set period of time, which is often sufficient.
