Grabbed the plat edition at 91% off (14.65 USD). Nothing could go wrong.
Still enjoying it in 2023 with new leader updates.

Kinda smooth, the performance is somewhat better than on Civ 5.
Late game slow turn changing can be eased with built-in 2D strategic view mode.
I usually do my city planning with that mode as well.
