In an FPS like Halo the relevance of skill sets is much harder to measure, but I think it's a delicate balance.
If I were forced to choose, I'd say motor skills and reaction time combined with spacial intelligence are the key drivers of success. I have yet to see an FPS professional that doesn't have tremendous shot accuracy and agility, relying only on their strategic skills. But I have seen some with great shots and spacial awareness make many questionable decisions. But my exposure is limited and my perception is biased.
I'd guess general intelligence shares relevance almost equally as it affects weapon utilization, detection avoidance, enemy action prediction, strategic positioning, verbal skills (team games), random trickery, etc.
