Depends on what you think "improves the game" though.
For some people the game may be improved by having 100+ extra sprites depicting every single model of every tank-destroyer in the world, and for some improving the game may involve having the border of Smallville, Nebraska moved 2 pixels to the northeast.
Thats true, I'm sure you want to pull your hair out with some of the crazy requests/complaints people have. :rofl:
For ME, the improvement in Vicky Revolutions was that Laisse-faire economies became hands off, low taxes allowed capitalists to do what they were intended to do.. build factories and railroads. Was vanilla Vicky good? Absolutely but Revolutions made the original look incomplete.
