I had it from release and honestly, even day 1 it smoked the competition in the city sim genre, releasing with features and scale than Sim City ever had.
The DLC often introduced more systems, but they did feel 'extra', the game was perfectly functional before parks or tourism or natural disasters etc.
The reason CS:2 felt so necessary is because the first was bloated and had underlying issues in it's simulation logic, like unrealistically inefficient driving, or a large expansion to residential areas causing all the new residents to die of old age at the same time, crippling the city. Every part of the GUI and logic just felt clunky compared to modern, polished games.
Back in 2013, I bought an old PS3 + GTA5 for £150 or so just to play the game, then once I had it, picked up two more exclusives, before never touching it again pretty quickly.
Getting a console for GTA6, plus the game, this time may set me back more than my expendable income after rent and bills. It will absolutely sell consoles but I'd wager people are actually able to buy a console much less than in 2013.
