rebuild-your-city-game the terrain would be there already (lots of ruins and obstacles and vermin) and your 'faction' would have to secure its position and resources. That style of game uses caricature icon 'units'.

Sounds like a mini-game for a MMORPG that you could play 'offline' while you couldnt be on your gaming machine for the main game.
