head to head
Dirt 5 asks more than Drunken Wrestlers 2, and the gap is optimization.

Execution · Pure Mechanics
Arcade car control across loose surfaces, weather and door-to-door packs.

Execution · Pure Mechanics
A physics-based wrestling brawler about controlling ragdoll combat against opponents.
Dirt 5 leans Execution (Pure Mechanics); Drunken Wrestlers 2 leans Execution (Pure Mechanics).
Dirt 5 leans a little harder on execution, though the gap is small.
Dirt 5
Sliding off-road cars on mixed surfaces is the whole test
Drunken Wrestlers 2
physics-based ragdoll control precision
Drunken Wrestlers 2 leans a little harder on reads, though the gap is small.
Dirt 5
Pack racing adds light wheel-to-wheel jockeying
Drunken Wrestlers 2
predicting human opponent's wrestling moves
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Dirt 5
Dynamic weather shifts grip unpredictably
Drunken Wrestlers 2
physics ragdoll randomness affects outcomes
Dirt 5 leans clearly harder on optimization.
Dirt 5
Car class knowledge and line choice reward study
Drunken Wrestlers 2
minimal, mostly reflexive physical play
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.
