The battles mainly take place in the virtual world. In Rockman, the enemies you fight are viruses, and you gain things after deleting those viruses. Same concept with SOA, you fight monsters, and you gain things from stuff they drop.
Another neat thing to point out, there are Charged techniques used in both series. Rockman's Charged Shot, and Kirito's Charged Slash.
