One neat trick to juice your interactions:

Make sure your game is partially non-functional. People will re-install in multiple times thinking the issue is on their side instead of reporting that something doesn't look right.

This is sarcasm, of course. But fixing my game so maps actually downloaded again dropped downloads/browser play count.

Finally getting around to proving out admin bounds logic in my demo project. I've had this data and setup in-place for over a year, but an error in merging data sets made it unusable in an unknown number of areas.

This year everything was done in one shot, no merging required. Plus adding in some features for flexibility that the core server's had for a while.
