Ok. So if I take my warp closers and stealthily cut someone else off from the rest of the map, does that mean that I've eliminated them? That would suck! Enough warp closers, and you are unstoppable! Just make a treaty with someone, place your WP closers on the strategic warppoints, then close them all at once. Presto, instant elimination!
Maybe the map should look something like the one in Adamant 4. There is an average of about 6
warppoints per system. (I'd really like to know how he did that!) It would be nigh impossible to play the turtle defense on that map, except that it's a cluster map. So there are strategic WPs to close. If it was midlife, with the same # of WPs....
