I used to play at a college gaming club. I was the rules guy, to a certain extent, so I've overseen dozens of people doing character creation. All of them claimed to be familiar with the rules.
Nearly 100% of them had some sort of character creation house rule which they were adamantly convinced was real. I had to get the book out to prove otherwise on innumerable occasions. They all loved rolling up new characters, but they tended to roll 7 stats and discard the lowest, 5d6 discard the two lowest, straight rolling but everything gets automatically increased to at least 10, automatic do-over if you don't get at least one 16, etc, etc, etc.
Yup. That's been my experience as well. I've never met anyone who wanted to roll their stats or HPs so they could experience the joy of roleplaying a gimp character with low HPs. Oh good golly no. I initially ended up converting to Point Buy, because I figured if everyone was going to keep messing with their rolls (either by cheating, or coming up with convulated rolling rules, or both) until they got the character they wanted, I might as well just cut to the chase and get it over with.
