I just read a review somewhere of the game, don't remember the site. But they listed lots of issues with the current game beyond the graphics.

I also have the game and I agree, it's fun and seems to work, but I haven't played that much yet. Kind of waiting for more fixes.

The one theyve acknowledged working on is related to garbage. Your cargo port/terminal will import a lot of various resources for your city to use, including garbage. Which means no matter how much garbage handling to build, your imports will flood it.

Workaround is to district everything and make sure your garbage handling facilities excludes the districts with the poets/terminals.

Some other economic bugs are not as bad. Like services not using resources correctly or zoned buildings having too much of a safety net for bankruptcy. Theres a lot the community is tracking down and the devs are working on.

I wouldn't say it makes the game unplayable. The complexity that does work is great. Its still so much better than CS1. Im not in the camp of anyone not buying "out of principal". Its a fairly small team who had a deadline to meet. They made a great game in that time despite the glaring issues. They provided 10 years of CS1 support (even excluding dlcs), CS2 will be no different.
