Regardless of what bobing just said, I do know the fun of enhanced urban combat. I made WR to support a system where you can tell the threat level of the garrisonning infantry by the pip colour. Green is weakest (GIs) and purple is absolutely deadly (for infantry that I will not name here
).
What's more, I made the vast majority of infantry able to garrison buildings. They all use different weapons, some AA... it's very intereting and fun to play.
