Since the trebuchets can also attack units directly, they're the star city raider until the discovery of cannons.因为投石机也能直接攻击单位，它们算得上是攻城利器，直到加农炮发明才会被替代。
Some might actually consider the trebuchet a bit overpowered but they're really only a problem if you let them get next 也许有人认为投石机有点过于强大了，但是他们只是在你让他们接近你的城市的时候才成为问题。
