I played it like a year after launch on PS4 and didn’t have any issues. On PC there is also ACUfixes that further fixes and improves things. Honestly Unity was such an ambitious game and both the city of Paris and the crowd system in it is still unsurpassed by later titles. I remember when Mirage came out comparison videos started going viral questioning which game came out 9 years after which. The fluid and varied animations in Unity is still absolute peak, look at how satisfying high level gameplay is.
