On the subject of Wasteland 2, Divinity Original Sin is really cool, it's all based around weird combos and stuff. Like rain spell, followed by fire to create steam that blocks everyone's sight, then create a flame pit and tele-slam a skeleton pirate into it. Plus it's funny.
I have Divinity OS in my backlog. I didn't get very far as I got it on console, and the controls added just enough of a barrier that I said I'll get back to it later. Loved the couple of hours I did play though.
