Rockman EXE 4.5: Real Operation is a unique spin-off in the Mega Man Battle Network series for the GBA. In this entry, you don't play as Lan Hikari; instead, you take the role of a NetOperator yourself. Players can choose from 21 different NetNavis, each with their own personality and AI. The game utilizes a real-time battle system where the Navi moves autonomously, and you provide Battle Chips to support them. A key feature is the real-time clock system: the game tracks actual dates and times, triggering special tournaments and events in the cyber-world accordingly. It offers a deeper, more immersive simulation of life with a personal NetNavi companion.
