Classify all games from Frictional (from worst to best)

[Googolplex]

Don't understand me wrong. Frictional Games never did a bad game (except the 2D games before Unbirth). They are now one of the BEST developers out there who always create brillant masterpieces! But let's compare them each other. Everytime we're talking about what's the best game, so I'm now interested to know what's the worst game in people's opinions. So what do you think is the worst game/expansion and why? From Penumbra and Amnesia.

1 = worst
6 = best


1. Amnesia: Justine
Too short, no kind of lantern, no saving option, less puzzles, no translation

2. Penumbra: Requiem
Too short, infinite batteries, no monsters, no translation, bad story (collect all orbs)

3. Amnesia: A Machine For Pigs
Almost no interaction, less and easy puzzles, bad credits song

4. Penumbra: Black Plague
Strange moments, Clarence's talking is annoying

5. Amnesia: The Dark Descent
Bad texts formulation, less challenging puzzles

6. Penumbra: Overture
No bad things - everything is perfect!
