Building comparison
head to head
Defense Grid 2vsWorld of Goo
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Defense Grid 2
Optimization · Pure Optimization
A classic maze-building tower defense won almost entirely through optimal layouts.
World of Goo
Optimization · Pure Optimization
A physics puzzle game about building wobbly towers and bridges from living goo balls.
Defense Grid 2 leans Optimization (Pure Optimization); World of Goo leans Optimization (Pure Optimization).
Defense Grid 2World of Goo
Axis by axis
Execution2 vs 3
World of Goo leans a little harder on execution, though the gap is small.
Defense Grid 2
Occasional orbital-ability timing, otherwise hands-off
World of Goo
Placing goo balls needs only mild precision
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Defense Grid 2
Fixed alien wave scripts, nothing adapts
World of Goo
No opponent exists
Variance1 vs 1
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Defense Grid 2
Spawn schedules are deterministic and previewable
World of Goo
Physics are visible and deterministic
Optimization9 vs 8
Defense Grid 2 leans a little harder on optimization, though the gap is small.
Defense Grid 2
Maze routing and tower economy are a solvable puzzle
World of Goo
Tower structure and goo economy are solvable per level
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.
