The Postal series is a bit of an underground sensation. Postal and Postal 2 are hideously offensive games that I hold close to my sadistic heart. The last entries were riddled with hilarities. Seeing as Postal 3 is being developed through the source engine, I'm thinking we have a pretty good chance of enjoying the violence in this one in glorious triple-monitor fun. It's currently set for Q2 2010, so we'll find out for sure pretty soon.
