Devs will abaddon this game, just like they did with
"Battle For the Galaxy".
They will left it half done, bugged, pay to win, and without support and updates.
I'm sorry to say it, but the card system really turned this game into, a money grabber.
After almost two month of playing I was able to upgrade my both HQs (ground and space) just by one level, and it is only because yo gave me some free cards on the first day of the update.
Then I will need another three months to upgrade any of them, on another level (six month for both).
It should be much easer to get the cards, and the space buildings should not consume them.
