>>> Even Defcon is unconventional. A game about nuclear war and mutual assured destruction with a retro asthetic

Don't forget the soundtrack! It added a lot to the game atmosphere :)

Especially the woman in the background who starts to weep as the first missiles hit their targets.

The weeping woman, the cough. Damn I am so tempted to play it again (does it make me a heartless psycho?), but I am at work :(

This is a great example of how some well though out details can play a massive role. Would the game be the same without the soundtrack, with the sounds of crying and coughing? It still would be a good game but not THAT good.

> but I am at work :(

You do realise that you are talking about the game with a work panic button built in, right?

Get your coworkers and boss involved, and then play it in "real-time" mode windowed over the course of a couple days. That'll keep engagement up.
