few questions ;p
1) small , big & energy guns = you want to tag one of those and stick to it (whatever you pick is also linked to your STR - going for big guns with 5 str is bad idea)
throwing - guess it counts as weapon skill too ...
2) unarmed & melee - like above but those are foe melee toons. I saw a suggestion on the forum that due to harsh wasteland environment its good to tag unarmed even if you go for ranged combat. I belive its wrong - you start probably with above 50 base in this skill and i dont belive you want to rise it above 100 points so taging skill that you want only rise by 50 is quite a waste - tagging skill that start at 20 and you want to get it over 100 is much better idea - Am i right ?
3) For some geatherables you need correct skill - like outdoorman science or first aid- are those good to sell if you aint crafter yourself ? few need outdoorsman - 40% its not many points to spend or is it better to save the points for other skills ?
4) Sneak ,steal & lockpick - either max if you go for thief or dont touch i assume ?
same for traps...
5) Repair - how much of it you need to not let your weapon break ?
6) First aid & doctor - do you need those to keep your ass alive or those are mostly reserved for crafting consumables?
7) Speach and gambling - are those used for anything here ?
Barter - quite obvious - but how are the numbers ? with 12% barter do you get 12% of cash you would earn with 100% ?
