With the right design, you should know what your funnel should look like.  With the right data tracking in place, you should know what’s happening in that funnel.  Next, you need to take action:

• Fix the leaks
• Nudge players to buy and upgrade
• Encourage happy players to invite their friends
• Ask unhappy players how to improve
• Offer lapsed gamers a reason to return
• Remind loyal gamers to renew and get ready for the next big thing!
