Great game - Though the ploy of me buying gems to feed the arcade is a little old. Only suggestion I have is to nix the "rest" timer, as I would rather pay gems for add ons, not to keep playing (and maintaining my stats). Played for 32 minutes = 51% rest gone.
Very much enjoy this game. Wish there was some profit / reason to join a gang (perhaps a ship created by the gang leader)
Some tips:
Get the best engines and then use hyperspace (W) and run courier missions.
Good combo for humans: Laser, Energy Extractor, LASS, Engine Overdrive.
Use (C) to pump energy into your shields.
Enjoy - I do!!
