- All weapons special effects would never trigger - They failed to dereference the index for critical hits, so the higher index the weapon had, the better its critical rate - A bunch of spells either don't work or have the opposite effect they are supposed to - The code for calculating run chance is so terribly messed up, it reads the wrong field from 2 characters down (so the last two characters read from some coincidental memory location causing them to be unlikely to run)
[edit]
Found a fairly comprehensive list of bugs; totaling nearly 50:

I guess it mostly comes down to the fact that players just didn't notice a lot of things (the "blind" status effect in Final Fantasy 6 did nothing, but this is really hard to notice as the hit chance it affects is called a chance for a reason) because they didn't know how things were supposed to work or they just worked around bugs if possible because patches often weren't an option.
[Edit]: I'm not trying to argue that the current way of things is in any way better than the old, both have their fair share of pros and cons.
Back then you had to be super careful about creating a strong product that wouldn't require too many updates. Now you have CI churning out multiple new versions a day, but one could argue we've got lazy about quality & documentation. And for the power user it was good to have complete control over whether you installed an update (and equally bad for the company because it was hard to know who had what version).
These days you have to look for release notes, newsgroups, Slack channels, Discord channels, tweets, FAQs, KBs, and so on to make sure you know what's going on. Gets a bit tiring. As a web developer I of course love the fact that I always know what version of the software my users are on, modulo browser differences.
Not arguing for a return to the past, not at all. I'm just saying that after 30+ years as a developer I don't feel that we've served customers any better in 2020 than in 1985.
