So I just tried FootLOL
Which is sorta like "Dungeon Keeper Soccer"

Now let's say you take this idea that began in Lemmings, moved on to DK and now FootLOL and add it to GTA style sandbox city where there are four warring factions. You play the role of Death and are focused
on one of the factions who makes a pact with you at the beginning.

The game would go on using special abilities and precariously placed physics to route the opposition (think "Fatal Attraction" )
while the faction you're guarding autonomously goes about taking over the city.
