As it says above, this kind of DLC is very situational. If you don't enjoy robots or a robot empire, then it's practically useless. However, if you want to play as either the Borg from Star Trek or the Geth from Mass Effect, then your money would be extremely well spent purchasing this DLC!

Kind of situational, but the extra stories / options this expansion offers are well worth the price!

Paradox may shine its brightest in this 4X space-faring game. Stellaris allows a player great diversity in creating unique alien species / societies and then playing out their story in a complex galaxy sized arena. The strategy involved in the game can be very in-depth and allows plenty of hours of game time. I highly recommend!
