I don't think you're quite getting what I'm saying yet,
@RevoluGame . A quick example:
Say there's a game that I
almost like. A way to figure out if I like graphics or gameplay better would be to ask if adding just one more graphic thing or just one more gameplay thing would be more likely to put me over into liking the game. But what counts as a "thing"? If the choice was between adding a dozen better textures to the game vs. adding a whole new class of skills, I would take the gameplay. If the choice was between adding widespread tessellation vs. adding one more skill, I would take the graphics.
That's what I meant by throwing the crazy, made-up units in there. I don't know how to compare the two things - they are apples and oranges to me. Maybe if I knew how much each one would cost then I could say which I would rather pay for.
There's one number where you don't need to units: 0. If I liked a past time with no graphics but good gameplay but not the other way around then I could say I like gameplay over graphics. But no such luck.
