wow 9+ are awesome, i love how there an giant leap from 7.8 to 9+ the difference in tactics is awesome. for example AI waves, the AI sends the wave to so they can then wait till they have ether more fire power or overwhelming forces to take you out. this most unique aspect of 9+ and doom is fact that no matter what they never directly send waves to you. because of AI doing this it somewhat buys you time to recover from attacks but they much more brutal than normal waves basically think of it as CPA every wave but only units from wave. this however makes game more interesting as you can in fact find these waves while they building up and some times when i done this AI has decided to attack and run away with units to one of systems it was going to attack thus leaving my fleet to deal with remaining AI forces on planet. and when you do successes in taking waves out they are good but it risky as they basically stalking the planet, and it can be anyone planet, however scouting is awesome, just in notes write down reinforcement numbers of planet then go check once while, and if there big jump then it AI wave. for this cant wait for day where they introduce 10+ (11,12,ecter).
