The units look great and heroes have backstories in their bio. The attack and defense ratios when inside enemy ships are off kilter even after armor upgrades for heroes. Battle Barge (your base.) upgrades after lvl 30 get insanely high like 75 million per resource to 31, 85 million to 32 and then 100 mill 33..etc. There is more, but will say this game is a grind and boring after 1 months timeformost none p2w players. I've played for almost a year. Don't bother if you can't give 50% of life to it
