I built this tool because I have hundreds of Android games from Humble Bundle and I'm not sure which ones I want to play first. play-app-ratings accepts app names on STDIN, one per line, and outputs a CSV with ratings and rating counts to STDOUT.
For my own case, I then applied a weighted average by hand and discovered I should play Kingdom Rush first, and it turned out to be a really well made game!
You must have Go installed and configured, after which you can run:
go get github.com/beefsack/play-app-ratings
play-app-ratings < game_list > ratings.csv
