The refund policy on the Android market has changed drastically in the last few months. There was a time when any of us could download a game and usually play it to completion within 24 hours if we wanted. If not to the end of the game, long enough to know if we were getting our money's worth (see yesterday's post).
With a 15 minute window, I am more squeamish about purchasing games, and especially those with notable after-install downloads, because I know you basically get one shot and a few minutes to decide if you like it.
What are the factors you are watching to decide if you want to refund in the first 15?
