head to head
Fallout: New Vegas asks more than Bloons Monkey City, and the gap is execution.

Optimization · Pure Optimization
Tower-defense math wrapped in a city-building economy to optimise.

Optimization · Pure Optimization
A faction-driven RPG-shooter where build and route planning shape every ending.
Bloons Monkey City leans Optimization (Pure Optimization); Fallout: New Vegas leans Optimization (Pure Optimization).
Fallout: New Vegas leans clearly harder on execution.
Bloons Monkey City
Tower placement is unhurried clicking
Fallout: New Vegas
Shooter inputs with VATS assist
Fallout: New Vegas leans a little harder on reads, though the gap is small.
Bloons Monkey City
Bloon waves never adapt to your defenses
Fallout: New Vegas
Scripted factions and enemies
Bloons Monkey City leans a little harder on variance, though the gap is small.
Bloons Monkey City
Captured tile layouts and special events vary mildly
Fallout: New Vegas
Some loot and crit RNG
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bloons Monkey City
Tower math, city economy and unlock routing are the whole game
Fallout: New Vegas
Faction routing, perks, builds heavily rewarded
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
