The 3DS Activity Log has the Software Library list, as you presumably all know, and of course also the Rankings. So this thread is for the Top 10 games you've played the most on 3DS according to it. Yeah. I feel like I don't have to explain this but whatever.

Mine are:
1. The World Ends With You: 56:20
2. Fire Emblem: Sacred Stones: 34:47
