Still not establishing a credible basis for the need to change. History isn't, for reasons I already presented and were not refuted. No criteria, no viable history-based argument on this, period. For an argument to be valid it must be coherent, and without that criteria it is not.
Paradox games, whilst sandbox-y at times, are still historical strategies. You can't compare them to Civ, which is pure sandbox.
Historical accuracy is a valid justification, we got so many mechanics or flavour in these games thanks to this justification, whether it be Janissaries, Colonial Nations, Japanese Shogunate, tons of flavour events, Absolutism mechanic, which make gameplay more interesting. If historical accuracy doesn't matter to you, then you wouldn't mind these things not existing
As for Absolutist governments being fragile, that is indeed true. Periods of instability or sudden crises toppled many absolutist kingdoms/empires, most notably France(poor harvest in the years prior to the revolution, plus thinkers challenging the divine right to rule) and Tsarist Russia(Russia spent tons of money funding the Okhrana and still had to fight off numerous rebellions and in the end the 1905 revolution forced Nikolay II to establish a constitution and form a Parliament)
