Despite having played and enjoyed Game of Watchcraft to bits, i would have to give my vote to the one game that ate a lot of my time, my wife's time, my brother-in-law's time, and my mom's plants... and time.
Same here, Gurk III is a compelling app with interesting combat and a huge world to explore. I considered Plants vs Zombies 2 but ultimately it's poor they encourage you to replay levels 4 times to acquire all stars and despite frequent unlocks feels grindy after a while.
