With Skill Points gained with Intelligence, the .5 carries over to even levels. Say you have a 9 INT, so you get 14.5 each level. At Level 3, you get 14. At Level 4, you get 15. You'll then get 14 again at Level 5, 15 again at Level 6, and so on.
That's according to the official game guide, at least.
Edited to add: Also, the number of implants you can get is limited by your Endurance. If you have an END of 7, you can have up to 7 implants. So, it's entirely viable to take a 10 INT right off the bat, because unless you have very high END, you'll be able to leave off a couple implants without it being a big deal.
Ah, cool. That is what I was wondering. Did not know the official game guide said that about skill points.
About the implants, I was just saying, if you are one endurance away from getting the intel implant, you could just drop the intel, bump endurance, and end up with the same intelligence.
Unless you can get just a total number of implants = to your endurance. Meaning you could get implants for a SPECIAL more than once, up to a total 10 implants, if you have 10 endurance.
I figured you could only get 1 SPECIAL implant per special. Did the guide say anything about that?
