+khailo and Ichse this make player can play on one mision and store a lot of tech for the next level you play the first level again and again for another level tech that mean tech is free you just need to play the first level
another thing and maybe the last thing is planet moving in v2 it shouldn't move like a circle every planet some planet move like circle some move like oval and some move to one side for a long time and range but only a little time in an other side speed is customizable too planet can't be crashed for a millions years there was no planet crashed in solar system and this war isn't so long like that
you want a new type of resource? now I found a new resource in galaxy harvest a resource named biomass is important the biomass is very slow so this will be used for a very few number you maybe even not needed in a start of a level don't try to add hydrogen nitrogen or oxygen it's so easy to produce water is from oxygen and hydrogen nitrogen found lot in planet's air earth's air (note nitrogen maybe found for a very small number in some planets you may add it if you think so)
I need to make a second comment to make it's not to long about trade and hired troops that fight for credit hire with credit and one thing about multiplayer you should be able to share your map some researchs that can be researched once unlock something like portal teleport fleet between planet with portal (cost energy too) some event blocker should be able to build like meteor detector that decrease chance of meteor will destroy structure and kill people solar flare detector decrease chance of destroying building by make it disabled for a while instead
v2 will have much more of the gameplay focus on the fleets. you will still grow your planets like you do now, but there will be more of a RTS element to harvesting resources. the fleet battles will be full on RTS, in 3d... , think homeworld style battles. bandboxing units, individual tactical commands for each ship. movement orders etc....
please make battery system to move or fight ships need energy (fleet can store limited energy battery ship store a lot of energy go to star with charger will cha rge energy more charger faster energy charging some research make your ship need less energy) you can ungroup into several fleets or retreat anywhere advanced planet terrain that have effect like cheaper building lower bombing strength you can only see enemy's starting spot then all enemy's out of line of sight is hidden you can spy with spy ship that can spy enemy's structure when it's unpacked it can sabotage ship's moving and structure's working thanks for reading this is so long
