how did you figure out what to do? Like +1 = say 25 xp? Something like that?
First thing to remember is in the conversion, you're not tryign to establish a points total but rather just trying to emulate the MW3 cahractersheet on a AToW character sheet.
Most of the stuff likes Atts , Traits and Skills and Skill Levels transfer straight across ie. A 100 point trait in MW3 is a 100 pt trait in AToW. If I have a MW3 character with Pilot/Mech 4+ they are going to have the exact same skill and level in AToW. The only real issues for conversion are when you run into deleted things like SOC, Traits (rarely) or skills (most common).
In the case of deleted Skills, a careful reading of the ATOW's Skill lists virtually always shows what the deleted skill was condensed into frex like how MW3's Bureaucracy skill has been rolled into AToW's Protocol skill. The only real exception that comes to mind is when you have the hyper-specialized skills in MW3 such as Gunnery (Ballistics/Lasers/Missiles) or the various skills covering small arms. For those, I use a judgement call. If all the subskill are within 1 or 2 of each other, I'll just set the relevant AToW score equal to the hgihest one from MW3. If there's a big points spread, I'll award the optional specialization to the highest one and set the skill level one below what it was in MW3. Frex. If I had a MW3 character with Rifles +4, Pistols +3, Shotguns +4 and SMG's +2, I 'd give them Small Arms +4 in AToW. OTOH, if I had a character with Gunnery/Mech/Ballsitics +2, Gunnery/Mech/Lasers +2 and Gunnery/Mech/Missiles +6, in AToW I'd give them Gunnery/Mech +5 with the Misisle optional specilization. On MW3 skills with exactly two specializations such as Piloting/Mech (Humanoid or quad), I base it off whether or not the have pruchased both specializations in MW3. If not, then I just treat it as a straight up conversion to the AToW skill, if they did, iuse the above paramters.
Deleted traits can often be covered by other AToW traits or Skills. The few that can't can be just plowed back into the appropriate Attribute(s). Frex. Magnetic Personality could be modeled by dumping the equivalent number of points into the AToW CHA attribute.
SOC is really the only oddball. If SOC is 3 or 4, I just ignore it as that's the normal range. If it's below 3 I'll either add a abd rep in AToW or if the character is from a society with "Citizenship" I'll nto give them that. If SOC is above 4, I'll model that by using an appropriate mix of Wealth, Good Rep, Extra Income and Property based on the characters backstory.
