Battle Network and Star force have always been my favorite parts of the Megaman universe entirely because these casts of characters were allowed to have conclusive endings unlike X, Z/ZX and Legends.
But the older i get the more i want to see the Megaman RPG's series revisited. The Legacy collection has put me in that mood.
I think it'd be cool if we got a new Battle network title where the new Navi's introduced are based on more X series characters like Axl and Vile, robot masters from 9/10/11, maybe even characters from Zero like the four guardians or even Quake Woman from the comics.
