Just picked up the GOTY edition which is $9.99, regular is $6.67 for next 24 hours. It's a steal! This game was retailing for $50 just a couple weeks ago. It runs okay with default settings (1280x800 all defaults set by Feral) on my 2013 MacBook Air i7, 8 GB, HD 5000. I get 23.1 FPS in their test from the main menu. So far I enjoyed the first 4% of the game. I need to read the manual about when things save though.
