In regards to speech checks, do you guys prefer the system from Fallout 3, or New Vegas?
In 3 for example, you could have 50 Speech, and when you talk to a certain NPC you have a dialogue option reliant on your Speech.
At 50 Speech in this example, you could have a 100% guarantee of succeeding.
But if you had 25 Speech, you might have a 40% chance, and pressing it could still make you succeed, although you're more likely to fail.
In New Vegas however, you could have 50 Speech, and when you talk to a certain NPC they also have a Speech reliant option, but it is not reliant on chance.
You need a minimum of say, 75 Speech to succeed. If you have 50, you will always fail, although will get an interesting/amusing piece of dialogue. But if you have 75 or above, you are guaranteed to always succeed.
So, do you prefer a Chance based system, where even with 1 point in Speech you might very rarely succeed the hardest challenge, or a minimum-level based system, where even if you're 1 point under, you can not complete the check?
