I actually enjoy games where I can script/macro my laptop do the work on grindy achievements. Not so much because I want the achievement/completion, but, rather, I find it interesting to set the tasks up on my machine and watch automation work its magic!
I have done Make It Rain (WP and W8) and am working on Lines: The Game (WP).
Does anyone know any other games that can be done through automation?
Yathzee perhaps. You wouldn't necessarily get the win every time, but you could script it to roll, pick the items in a certain order beneficial to player 1, and less so for player 2. Rinse repeat a bajillion times to get the 100 wins.
Bejeweled Live, you could have it try every move in sequence, starting over when it hits the end. Eventually it would make a match, and could grind out those million gems my wife is still trying to get before you do.
That's about all I have on my phone currently that I could come up with. anything requiring the same repeated action over time or a certain number of games played would work though.
