head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
Budgeting steam movement and loadouts against hidden but scripted alien positions.

Optimization · Pure Optimization
A bleak turn-based RPG where every gain costs you something permanent.
Code Name S.T.E.A.M. leans Optimization (Pure Optimization); Lisa: The Painful leans Optimization (Pure Optimization).
Code Name S.T.E.A.M. leans a little harder on execution, though the gap is small.
Code Name S.T.E.A.M.
Manual third-person aiming adds a real but small hands layer
Lisa: The Painful
Timed button inputs spice up turn combat
Code Name S.T.E.A.M. leans a little harder on reads, though the gap is small.
Code Name S.T.E.A.M.
Alien AI runs fixed behaviours, never modelling you
Lisa: The Painful
No adaptive opposition
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Code Name S.T.E.A.M.
Unseen enemy positions and overwatch threats are hidden information
Lisa: The Painful
Russian roulette and permanent random losses
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Code Name S.T.E.A.M.
Steam budgeting, loadouts and positioning are the solvable core
Lisa: The Painful
Party builds and sacrifice decisions are strategic
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.
