Vicky 2 was of the older generation of PDX games. Pretty much everything post CK2 should be in its own category and really not compared as they followed drastically different business models. That, and the fact that Paradox absolutely ballooned in size since then mean that comparisons for copies sold is just substanceless padding on your terrible argument.

A House Divided came out in 2012 (CK2 era) and Heart of Darkness came out in 2013 (EU4 era). Compare it with any imaginary era you had of PDX in your mind, Vicky 2 wasn't the smashing hit success you like to think it was. CK2 got several DLC's in its first year, a model that could of been easily transferred over to Vicky 2 if the numbers were there for it. Coulda done the same thing in 2013 when EU4 got 4 DLC's during its first year as well. Are the numbers above perfect? No. It's using vginsights. But they're good enough starting points.
This right here is the problem - pandering to players who want to make the game more boring. Tall is easier, safer and less effort and requires less strategy than playing wide. Any "struggles" that a tall "player" will face is something that a wide player will also face, but on a wider scale. Playing wide requires more diplomatic skill, since you tread on more toes. Tall should never be a valid alternative to wide.
Playing wide is less skillfull, it's just pandering to bad players who don't do any real development and just bumrush the AI nation in the early game before it can set itself up properly to counter a human player, annex them, take over all their development, and go on a conquering spree until no AI nation can stand up to him. Playing wide is easier, safer, and less effort and requires less strategy than playing tall. A tall player has to actually
think about what he's doing with his limited resources while any "struggle" a wide player has he just steamrolls over because he just snowballed out of control.
Anybody can say stupid crap to feel smug. Stop having the equivalent of a shower argument 2 days after you got roasted by someone and finally came up with a good comeback in a public forum, do it in the privacy of your shower like the rest of us do.
