the low number of skillpoints is interesting. for the demo my guess is that they put int at 5-6. Since if you get base stat *2 as starting skillpoints. it looks like most of the skills have gotten a few extra points andscience speach gotten about 20 extra. which would compute if int start on 6 and you gotten 5 levels of skills points. The plus markers seems to anote tag skills. This also means that the tag skills from start dont give you a ton of skillspoints as it did in failout3. whre one left the vault with 3 skills at around 35 and about every other in 20 at level 2. this is good new since it means you cant go jack of all trade as in f3 but you actually have to concentrate on what you want your character to do.
