I can see where you're coming from when you say that having to go out of your way to get a perk that in theory perfectly matches your character. One thing that I've learned to accept is that for the most part, devs have thought about every little issue infinitely longer than any of us to ensure proper balance. I don't want to need 70 Science skill to make devastatingly powerful Energy/Microfusion Cells, but I'm going to have to if I want my character to go the way that I planned. Oh, and as for the whole 1/2 skill point thing, it seems somewhat reasonable. With INT 10, after you get Educated (assuming you will), you will earn 442 skill points between levels 4 and 30. There are 51 skill books of 3 points each (or 4 with Comprehension) for a total of either 153 or 204 points. You'd be able to completely max out 6 skills. I'm kind of worried, but not as much as I was before. Some gameplay vids that have been slipping by ZeniMax since the floodgates of early acquired copies have opened show people with relatively high skill levels at level 2 or 3.
Most of my builds in F3 consisted of two maxed out weapon skills, repair, either lock picking or science, then a couple others depending on the build. Sneak, medicine, speech... I seriously maxed out repair with every character regardless of the role play. What about you guys?
I believe it works like this.
it's .5 per intelligence
So in other words, this is how many you get per level with each Int.
1 - 10.5
2 - 11
3 - 11.5
4 - 12
5 - 12.5
6 - 13
7 - 13.5
8 - 14
9 - 14.5
10 - 15
