Recording metrics?

Player prefs gives you the capability of writing key / value pairs to a text file stored locally on the mac$$anonymous$$ne that the client is running. With "metrics" tracking such as yours, you're looking at creating database information. So, you would either have to learn how to create your own databases and make query calls ( take for example SQL queries ) to your database server to store the information, or look for a vendor that supplies these services.

There isn't a one all solution for t$$anonymous$$s if you decide to create it yourself. Another option would be to go to a t$$anonymous$$rd party analytics platform that stores t$$anonymous$$s information for you. Flurry is a good example of t$$anonymous$$s, and would do exactly what you're wanting:
