Great on voices, very flexible on rule of cool.

Crono knows how to use the virtual tools better then any other GM I've played with. When your screen has an issue he can quickly resolve. He knows the rules and can actively assist you and other players with actions. Your not having to struggle to figure out how to roll dice. Your also not having to wait for inexperienced players to figure out how to roll their dice. This allows a lot more time for content and roleplay.
