So I've been talking to some folk about putting together an urban horror game using the Cinematic Unisystem. One of the issues generally brought up when we speak about this system is Dexterity and how it potentially breaks the balance of the game at higher levels. I'll explain below.
At higher levels of Dexterity players start getting extra actions every turn. At Dexterity 5 and 6 you get +1 action, at 7-8 you get +2, at 9-10 you get +3, at 11-12 you get +4, etc. These extra actions may be taken as extra attacks or defenses. Each action beyond the first suffers a cumulative -2 penalty.
Example: A character with Dexterity 7 can declare up to 3 actions in a turn. Say he's fighting 3 vampires and wants to attack each of them one time so he declares he's taking 3 actions, all of them attacks. He makes a single combat roll, getting a 20. He compares the roll against the first vampires Combat skill (a 19) and notes a hit. He does damage and moves on to the second vampire. He takes his initial roll of 20 and subtracts 2 adjusting it to 18. The second vampire also has a Combat skill of 19, however, meaning the attack misses. Because this attack misses he does not get his third attack.
While a Dexterity of 7 is very high for a character it is certainly possible, especially for a vampire or other supernatural creature.
Thankfully the designers of the game actually address this potential issue and give some alternative ideas. This is the rule we use in my TT group and one I'm thinking about using for the game I'm working on.
Alternate Rule: Any character can attempt any number of actions they want in a round. Before they act they declare how many total actions they want to take. Each action beyond the first adds -2 to all actions that turn. So in the above example the player declares 3 actions incurring a -4 penalty to all his actions that turn.
We've found this to be pretty balanced and generally keeps players from just pumping points into Dexterity to get those extra actions.
For those familiar with the Unisystem what are your thoughts? Do you house rule Dexterity? If so what rule do you use?
