Most people I know, including myself, that work the 60+ hours do so because they absolutely love it (and ofc they do get compensated and noticed for it). Also, the biggest advantage is that when the place clears out after most everyone goes home (because there are some people who routinely punch out after 10 hours of work), it opens up a huge opportunity to experiment with potentially neat ideas among the people who stay. I've seen a lot of neat ideas come straight out of the after hours, and it would not surprise me if a lot of the cooler mechanics we see in Skyrim were the result of some employees staying late at night saying "dude check out what I just did!"
Wouldn't it have been better for that creativity to be present during work hours
and you got to go home normal time? If you're not overloaded, not overworked, that's possible.
Mostly, though, while I can appreciate the drive passion gives you -- been there, done that, worked my 100 hour weeks before -- you need to remember one very important thing: doing so reduces your value. If the company pays you a salary of X for a 40 hour week and you work 80, you're working for half the amount of money you actually deserve. And if you're willing to do that, there's no incentive to pay you more, because you're demonstrating you'll work for less. This is very important -- what you are paid in a role isn't just what the job was advertised for, it's what you're willing to accept. The last full-time job I interviewed for the salary wasn't quite what I wanted, but I went along anyway because the company sounded good*. When they realised they wanted me and asked what I expected for renumeration, I told them what I expected -- my value. It was higher than they had allocated for the budget for the position, but they went away and came back with a counter offer that was close to what I asked, and substantially higher than the advertised salary. If I was someone who didn't value myself higher, I would have asked for less, and got less.
Don't devalue your work by working more than you're being paid for -- I know this is hard sometimes, I've certainly done overtime in my roles because I care about the product, but make it the exception not the rule.
* The other thing about interviews -- it's not just them interviewing you, you need to interview them. Not only do you get to find out more about the role and the company, but merely asking questions that demonstrate that you haven't yet decided if
you want to be with
them gives you value in their eyes. After all, if you're finding out if they're good enough for you, then you must value yourself and when it comes to asking you onboard they will know they need to pay you enough to match your value.
