Pangea Arcade is free on the Mac App store right now. There are 3 classic arcade games in this app based on Centipede, Asteroids and Missile Command so there’s plenty of gameplay on offer here!
I’m trying to install it but the App Store has frozen on my machine. Hopefully it’ll stop being a buggy POS sometime this morning so I can download this. *sigh* (Thanks James for the news!)
