Ratings and reviews

Let's do the math. The largest island has ~250 buildable spots. There are 8 islands, let's say they all have that space available (they don't). At lvl 44 you need to produce 32.9AC. The max level highest tier generator produces 51.9AB. It take 98% of max/highest reactor. So 1:1. It takes 3 heat sinks for the waste heat (which doesn't make sense). That's 5 spaces needed. The best you can do with the biggest island is fit 50 of these. You need 632 to meet the goal. This is mathematically impossibl

I'm having such a great time, planning to get the VIP pass for life. however, is it possible to mute Karen? the sounds she make when interacted with are seriously upsetting and an ear sore against the relaxed music. thanks

3 star because I still play the reacter 1 and it's to good but in this one the Main paly is changed like it's totally griendy more than the reacter 1
