So with all the information on character builds, I was trying to throw in some calculations and please correct me if I am wrong anywhere and I'll edit this.
So if you take an average character:
STR 4, PER, 4, END 4, CHR 4, INT 4, AGL 4, LCK4 : which is your total of 28 initial points.
To max out these stats as early as possible, you would need the first 42 levels of your build.
Then to max out stats (and I am assuming with given information and not speculated) you would need an additional 270 levels to max out all perks for the GOD BUILD. I haven't exactly went onto orcz.coms perk chart to get each rank, but TH did say there was a total of 270....
This is not taking into account the Magazine Perks and their rankings... which I assume would be immediate and not need leveling.
So for GOD MODE, you would need a total of 312 levels to be maxed out.

Calculated each rank from the confirmed perk chart with the 42 levels needed to max out your characters SPECIAL and its a total of 271 levels.
This is not also taking into account whether or not bobbleheads give a +1 to whatever stat anymore. If they do, knock this down 10 levels.
My original concerned would be that yes they did say they did sped up leveling but still, it would a long time to get everything maxed out legitly. My concerned is theres a lot of choices for me and not enough time to get these maxed out.
