I agree that RGL is a great addition to the game that (much like seizing the initiative) forces players to worry about things not going their way. I think the ire on the internet is not so much about RGL but about situations where a fast enemy gambles on the game ending and wins by last turn contest even if they are "losing" from VP standpoint.

In 6th edition I would like to see random game length continue, but I am intrigued by the idea of accruing points every turn for holding objectives. But to play devil's advocate, the downside of this is one player could already have effectively won the game by turn 3. They need to make sure there are still ways the other player can try to win (perhaps VP or tabling).
