I stumbled across this looking for games similar to those we’re discussing in class.  It’s a big archive of social realist games, specifically those designed for a certain real-world effect…hence the name.

Some of them are playable online, some aren’t, but they all have little summaries that give you an idea the sort of complex social subjects people are modeling.  It’s amazing the huge variety of nuanced subjects people feel capable of simulating; there’s everything from conflict and environmental disaster to poverty and public policy.
