IGN
One negative note is the inability to use and integrate older save files. This means that some features of Late Night do not integrate with older versions of The Sims. Since The Sims franchise has typically fostered backwards compatibility and integration between expansions, this design flaw was particularly irritating for a large part of The Sims' fan base.

IGN rated the expansion as 7.5 out of 10.

Games Radar
The review noted the vast amount of new features and gameplay options, and praised the new ability of reaching celebrity status; however, Games Radar, like IGN, did not like that players basically need to start from scratch with the Late Night expansion due to lack of integration and backwards compatibility. Another knock on the expansion is that, oddly, the night life sometimes felt "dead."

Games Radar rated the expansion as 7 out of 10.
