Sure, but what I meant is that good developers took a lot of care in ensuring the game was ready for release, and companies like Nintendo and Sega did a lot of checks to ensure there were no major issues (for example, they’d keep it running for a long time while monitoring memory usage to ensure there were no memory leaks).

These days, some games need a patch within the first week of release. Manufacturers have gotten lazier in terms of ensuring the game works properly, since they can just patch issues after release.
