I decided to try the game again now that it is f2p. I bought new graphic card meanwhile
and my machine can run all at max. Let me tell you something: graphics in this game are bad. But this was not my issue - I can bear bad graphics.
One other thing made me just close the game and uninstall. I couldn't believe it but you must actually pay to have additional quick slots.
They didn't learn anything they are still very gready.
