Big cityscape concept art for a dream game project mine, Project Amabie. It's intended to be a successor to the Mega Man Battle Network/Star Force games, hoping to build upon what those games offered in some better overworld movement.
This area is a shotengai shopping street somewhat based off architecture from Koka, Shiga Prefecture in the Kansai Region of Japan.
My plan is the protagonist can switch between a human and cyber form, where you can introduce "augmented reality" objects to the level that now become tangible.
In human form you'll traverse the area like any normal person would, but in cyber form, you will lose your ability to lift physical mass and won't be able to do certain mundane tasks like twisting the doorknob to open a door or pick real world items off the ground. Therefore you'll have to take advantage of the AR objects and use them to zip across rooftops and find more electronic means of sneaking into places, than just the standard human entrance.
