Mega Man Battle Network 6
From The Rockman EXE Zone Wiki
Smoothest gameplay in the entire series! Makes you feel like a divine-being with less customization limitation, overpowered chips, and weak bosses! Also extended the Chip gate and PET compatibility to the max with the Amiibo- I mean the LiNK Navi System! The final game in the series, but somehow the best game to introduce someone into the series!
