Let's say you play in a system where players roll Attribute + Skill and try to match or exceed a target number set by the GM based on his evaluation of the difficulty of the task.I don’t want to be absolutist about it, but I probably won’t use the Attribute TN mechanic. This one really needs some explaining beyond “it makes a solo play mode possible.” Because I just don’t get it.
Let's call this game BE&E.
For two players with the same skill level but different attributes, one will have an easier time than the other because of a higher attribute.
How is that any different than what TOR 2nd proposes?
In other words, for two persons with the same training (i.e. skill), the one with more natural talent (i.e. attribute) will have an easier time of succeeding.
Now, that might be something that you don't want in your game, and that's perfectly fine. To each their own.
But I don't think it's THAT revolutionary of a game mechanic. The only real difference with countless other RPGs is that instead of adding your attribute to your skill, you substract it from the target number.
Mathematically, it's exactly the same thing.
