i see your point. i'm still thinking about how i'm gonna do it, or whether i'm gonna do it at all. what you're saying is for apps which is a different experience. i have yet to see a game where you have to press ctrl+tab to go back to windows and copy paste your private key. at that point you're probably better off creating a simple game or an app that runs in your browser. i think cryptokitties is a good example.

if i'm using unity and the core gameplay is arcade/action i won't do it.

if i'm making a game where the core gameplay is in social content and blockchains then yea, integrating steem would be perfect.
