While DPC can perhaps write a completely authentic Swedish college experience (with everyone authentically speaking Swedish, referencing Swedish pop culture and slang), all that will do is reduce his potential market by 99%

.
The power of the
English language and as
vir_cotto pointed out, the power of hollywood compels the vast majority of games to be set in some generic US (or occasionally UK) setting. That's why even games written in Engrish so bad that one can hardly understand what's going on (and one knows for sure the Dev has never set foot in an English speaking country) are still set in some random town/random school USA.
Indeed, indeed. Fun fact, only 14% of f95 users live in N.America
survey says , so for the other 86%, interpreting whether DPC depicts things correctly or not
is itself based on their/our interpretation from watching of US movies and TV shows

. So if we go with authenticy compared to American Pie, Animal House, Flatliners, Spider-man 2, Monster U, Good Will Hunting, The Skrulls etc. I think DPC is doing well enough
