There is no fun in playing when it is obvious that you are lost and I would actually feel betrayed if you would let me win on purpose, for you treated me like child and in a dishonest way. I'd rather face reality and learn from it. Maybe your dishonesty is why you are still ahead of your friends?

On the other hand, I once played a game where I was clearly loosing, but got really disappointed by a sudden death caused by caelian flyers occupying enough victory points at the other end of the world in an instant without everybody noticing. I new that I could not win, but being Miasmal Ctis it was kind of fun to watch the Ulmites die of poison and disease at my Lizard's Hill Fortresse's Gates by the dozen. All the umlish steel waste by swamp disease and poison slingers! They managed to storm a fortresses here and there, but at what cost! That was fun, despite of loosing in the long run and I was disappointed when I learnt what Caelum was doing...

So if you are merely considering such a "sudden death" move and would loose against their combined forces in the long run, then I would just ask them whether they have still fun.
