The building crowd should like this. http://store.steampowered.com/app/268650/?snr=1_7_15__13 Sorry for the let's player. His dialogue explains nothing, but he does show the building system quite a bit.
I'm necroing this because I've been playing this for the last few days. I suck at it, and I still love how it plays out. You can build so much cool stuff, It has a campaign in a huge open world that involves you using your creations to take out other factions. It also has multiplayer coop, but I've not been able to do that yet. It's been a long time since I've had fun in a game like this.
