I think KPI on itself is fine, it's basically the goal of the game you are playing, defining it clearly should help. However, it never make sense to to have multiple KPIs, everything should be derived from a single KPI.

This actually give KPI some weight, because it literally defines what you do. Whenever you define you KPI, you'd think, "okay, is this all that I'm doing now?". And whenever you change your KPI, you'd be thinking, "okay, should I abandon the last game I played and play a new one?".
