I'm well aware of what dopamine does. There's a long, long stretch from "what dopamine does" to "Civ 4 had a constant stream of small rewards that stimulated the release of dopamine."
You don't connect the two at all, you just rely on people who agree with you already to smile and nod when you hand wave your way across the big leap in logic.
Your post basically says, "Purple is a color, therefore oranges are a tasty citrus snack!" The first part is a fact, the second part is pretty much an opinion dressed up as a fact, and you never really connect the two.
You accuse me of being offensive, but this sort of posting is pretty offensive to me. Maybe I'll make a thread that explains why Søren Kierkegaard's writings prove that Civilization 5 is the fundamentally correct choice in gaming for each single individual.
