There's a G-Mod mod for dressing up the citizens in different colored suits, found here. I thought brown looked nicest on Frohman. And, there's a complete DoD mod as well, that gives you all the models and weapons and stuff from DoD:S. People make cool stuff.

I'll probably have a review of Episode 1 up in a few days, if you're still on the fence about buying it. Short answer is, it's worth it. But I'll have more to say in a couple days.
