I need to recheck some of these games but I'm leaning towards investing a bit in dcrops. Patient my waiting for unsung heroes as well. I tried out lost of these and some seem a bit point less after a while. Like holybread for instance. Ocean planet seems very cool but you need to focus on what you doing so something that requires a bit more time I guess.

Spliterlands and rising star still my top choices for fun and low maintenance!
