Ok...

I don't know if you guys are talking about solo play or PBW here, but I've been in PBW games where 300% or even 400% would have been too low. It's entirely possible for the 1st place player to be that much stronger then the 2nd place player and still get beat if the others gang up and play a good end game. Especially since score is so easy to manipulate by building lots of cheap, low-tech ships. And as bad as it is being in a game that seems to drag on for ever, it's much worse to have what is shaping up to be a really good ending to a game be aborted by an arbitrary limit.

I second that Geo. In TGE3, my score was above 300% of the second player for many turns, and I did not even play to have the highest score possible (that was just my usual Base Space Yard/Light Carrier production). It would have been very easy to create even more inflation, by building empty starbases, or something along these lines. But I was still a long way off from being able to take on the whole galaxy on my own, though a few Empires would have suffered in a global war.

I would much rather vote on ending the game, when it looks like an Empire cannot be defeated, no matter what. NGC3 ended a few turns before the final clash against the leading Empire (we would have been crushed, but still, it is much better to be defeated in the field than by numbers).
