luck, int, agi and strength are my picks. i like to sneak about also, so my characters tend to be a bit flimsy in a toe to toe battle, but a high luck and high agility means more crits and more action points which help a great deal early on (early on... i'm going on FO3 experience here, still exploring goodsprings in NV

) int for skill points and a passive increase in medicine and science, strength for extra bag space, and the odd occasion i have to resort to melee. endurance is ok but if you crit 3 times in a row from a distance, whatever you're shooting at wont be alive enough to be troubling your health pool, plus i'm assuming that your resistance to damage effects will increase naturally as the game progresses (perks, gear, etc) charisma i set at 1, if i wanted to make friends in a game i'd play an mmo. perception is... mildly useful for a sneaky sort (radar range), but no more useful than 4 or 5. wear a hat with +1 per if you really want to know what's coming
