I love this game. I play it all the time. Not a lot of ads either and the only ads you see are by choice! The trick is to get you energy storage and regen stats high right away using the materials maps. Then you can do a lot more a lot faster. Events are fun too! Storyline isn't important to know what to do either if you want something mind numbing. And if you like them, the stories are entertaining too so it works both ways.
