Here's a template that might work:
It's official name is Strategic 4v4, but I like to call it Quest for Excalibur. It is played on the Europe AD 1600 map, a great map for 4v4s.
BTW, I really think Hong Kong is a boring map, don't really like it. As for Rise of Rome, I absolutely HATE that map. Please don't choose that one; the drawing is so awful.
