Having watched the new Ant-Man movie recently, the thought of using the same concept for a game appealed to me.

Mostly, the game would be based around timed situations where the player would need to switch between sizes - basically, a choice between size and speed. However, as the mass of the player does't change, the smaller form would have added strength and durability, as well as maintaining it's velocity. (As an example, building up speed at human size before shrinking to use the velocity to pass trough a trap or small gap in midair.

If combat was included, the player would be able to maintain stealth while hitting enemies with the same force as their larger form. Given the ability to communicate with/control ants that is part of the Ant-Man theme, it would make for an army management and strategy game that actively rewards stealth.

And open world sandbox game play could allow me to play Simant again and drive the neighbors out of their house with an infestation of ants.

I miss that game.
