Jason Rohrer is a quite controversial independent game developer with a track record of thought provoking games. His latest offering (in alpha state for 50% off sale with public domain source code included) The Castle Doctrine is a MMO about "burglary and home defense". Better than I could do it here shortly, these two (1, 2) articles give you an idea what the game is about.
|Build defenses to protect your family or is it just another puzzle to solve?|
On an unrelated note, one of the guys behind last year's successful FOSS board game Kickstarter project A Las Barricadas, is now looking for financial subscriptions for him to create more FOSS art (CC-by) and to take some art classes the same time. If that sounds like a good way to spend your hard earned cash, check out some of his previous works here.
