Games to play while listening to podcasts? Looking for some games that don't require too much focus to play and aren't heavy on story/dialogue.

Games I've tried so far: 

* the CIV games
* GalCiv2
* Endless Space
* Minecraft
* Terraria
* Just Cause 2
* Homm 3/5/6
* Dungeons of Dredmor
* The Binding of Isaac
* Dungeon Crawl Stone Soup
* Super Meat Boy 
* Spelunky
* Battle for Wesnoth
* Frozen Synapse
* Trackmania

I'd be grateful for any suggestions.
