I've taken Pink's THIRD capital and I'm confident to say they've been all but destroyed. Their population is less than 10% it was at their peak, their remaining military is only barely stronger than Blue's (solely due to their huge starship fleet), and their industry is crippled beyond repair. So much for the oldest of empires.

Blue remains a rogue state, slow fleets are slow and won't arrive for five more turns. Ironically my war against them lasted longer than my blitz against Pink. Sure Blue's final world will fall before I finish exterminating Pink, but Pink is literally just a corpse empire right now.

Finally Yellow has given me a massive opening. Forces stationed on their Industrial Complex are "relatively" weak. With my solid foothold in the center of the map and the clearing of Pink's minefields, I'm now able to amass jumpdrive warships from all my territories to surprise capture the massive shipyard and its surrounding worlds. These attacks will probably cost half my jumpfleet, but the gains massively outweigh the cost. In six or less turns I can have a solid foothold on the opposite side of the galactic map and steal a major source of Yellow's industry and use it for my own. It won't be quite the decisive blow like surprising Pink's capital was (most of Yellow's fleet is concentrated on their capital), but it'll be an amazing beachhead.
