I got my money's worth from the original, but I have two major complaints about it that, from what I can see, the new game doesn't address:

First, the developer originally made transport games and that bias shows. C:S makes it incredibly hard to design a city that isn't car-centric, and gameplay in practice tends to center on optimizing car traffic at the expense of everything else a city-builder could be.

Second (and this ties into the first, to an extent) is that the game doesn't represent the passage of time, in a technological or societal sense. Real cities grow and change over decades and centuries, with decisions made in prior eras imposing informing and imposing restraints on those made after. C:S cities exist in a weird, timeless and anachronistic "now" from the start. This was something that classic SimCity games did well, at least in the context of an American boom town: as the years advance, so does the tech tree, opening up new mass transit options, cleaner and more efficient infrastructure items, and new kinds of commerce and industry.

Personally, I'd love a game in this genre that plays like SimCity but takes in the whole arc of history, say from from the Middle Ages onwards, so that players can start to appreciate how decisions they make hundreds of years prior can leave their mark on the city in the present -- for example, where a defensive wall gets placed during a medieval time of war leaves a mark of the street networks, and changes the way that that social classes distribute through the city and leads to a high-rent luxury district in a future era.
