Cliffski’s Gratuitous Space Battles has been released for Mac:
GSB is the ultimate space strategy game. It’s a strategy / management / simulation game that does away with all the base building and delays and gets straight to the meat and potatoes of science-fiction games : The big space battles fought by huge spaceships with tons of laser beams and things going ‘zap!’, ‘ka-boom!’ and ‘ka-pow!’.\
In GSB you put your ships together from modular components, arrange them into fleets, give your ships orders of engagement and then hope they emerge victorious from battle (or at least blow to bits in aesthetically pleasing ways).
I got a copy for PC a while ago but I’ve been holding out for the Mac version. Kapla!

Nice. If only I knew if they have any plans on release it on Steam. There is a -75% off price campaign there just for this weekend and I’m pondering whether to buy it or not.
