Hi. I know that there are quite a lot sniper builds on the web but I really wanted to make my own. It doesn't have to be the best. It just has to work properly. I've beaten the game only once so I'm not a pro and I wondered if my ideas could work ingame. I'll just present overall stats.

S.P.E.C.I.A.L
Strength – 3
Perception - 8
Endurance - 4
Charisma - 1
Intelligence - 6
Agility - 9
Luck - 9

I know that 6 strength is required to carry a sniper rifle but I'll be (I think so) able to carry it later, on level 16 (intense training = +1 strength; weapon handling perk = a sniper rifle requres 4 strength). Just let me know if this will work (since I don't want to get to level 16 and learn that the whole build was pointless).
Another question - does the higher game difficulty determine the (lower) amount of exp. points you get for killing enemies or does it just develope AI and make them harder to kill?
And sry for my English. It's not my native language
