CCG writes – Despite the slow pace and lengthy animations, GrandMa Bad*ss is a pretty good time. If you can get past the raunchiness (that does tone itself down a little the more it goes on), youll find a surprisingly wholesome adventure underneath about a cool grandma who just wants to save her cat. The humor is pretty funny at times with character interactions and cheeky references to movies, TV, and other video games. It took me about 7 hours to get through it with some assistance from a guide but will range somewhere between 6 and 10 for most players. Whether you play it once and put it away, or you go after the multitude of achievements, I can recommend this to an adult audience who may long for older times starring a pretty kick-butt granny.”
