Yes, I'm actually somewhat serious. We should have a gamemode depicting communism.
You would be playing as someone living in a Soviet-era Stalinist land. You're constantly starving, living in poverty, required to put everything into a community chest for "equal redistribution", and brutally oppressed if you dare go against the government. The quality of food and life in general would be extremely shitty, with a 50% chance of being poisoned by the food you eat. Corruption would be widespread in the government. You would be able to bribe the police into looking the other way. If you get caught doing anything pro-capitalist, you are immediately sent to a gulag. If you protest against the government or its glorious leader, you will disappear.
I think this gamemode would be hilarious to play on and would give people a choice of how free they want to be. It would also have great meme potential.
