Shooter inputs with VATS assist
Lords of Football
minimal direct control, management focus
Lords of Football leans a little harder on reads, though the gap is small.
Fallout: New Vegas
Scripted factions and enemies
Lords of Football

Lords of Football leans clearly harder on variance.
Fallout: New Vegas
Some loot and crit RNG
Lords of Football

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
Lords of Football
squad management and training dominate
