Crunchy, chewy, brain melting....whatever you call games that give your brain a workout, this is one of the best. 'Do a thing to uncover a thing to get more things' is what this is about and it does it so well.
The game has very little randomness so it's a very deep strategic game that will keep you engaged play after play. Each of the factions has a different approach so you'll have unique experience every time.
The solo mode is brilliant and most importantly very easy to run so you spend more time focusing on your engine.
HIGHLY recommended!
