Time to Take Out the Trash
...by picking it all up and dropping it off in the waste receptacles provided. Sometimes the life of a video game star isn't all excitement and explosions and alienating boob jiggling; occasionally you're required to do something as banal as fetching some guy his newspaper, weeding the garden or, indeed, litter pick-up.
What we have here is a game currently in development that thinks it can make an entire game out of humble janitorial duties, and a nonet of games that have actually made it work. With varying levels of success.
(P.S. I'm not including any playable janitors if they don't actually do any janitorial work and instead run off to save the world. Those guys are dead to me. You heard me Abe of Abe's Oddysee and Roger Wilco of Space Quest!)
