Trying to duplicate Fallout as closely as possable I'm going to base skills more off of Fallouts skill set but also throw in a few of the 3E skills for things that the game doesn't cover such as Jump and Balance.
Also, I'm going to base the basic attack bonus off of skills like in the Fallout world. Here are the skills I'm planning on using.

There won't be any class skills, you can take however many you want of whatever you want however as you gain more ranks it will take more skill points to buy each rank. At the moment I'm thinking
1-5 ranks = 1 skill point
6-10 ranks = 2 skill points
11-15 ranks = 3 skill points
Also, each player will be able to pick 3 tag skills at 1st level that allow 1 skill point to count as 2 for that skill. Skill points will be half your Int score plus Int modifier
