60K seems like good money for an entry-level game programming job. I wouldn't count on any profit sharing or equity to be worth anything. If it is, great, but don't count on it.
The game industry is organized kind of like the music industry. Small studios are the bands to the publisher's record companies. Small studios (typically under-funded and over-ambitious) beg the big guys for money to work on projects. They often get screwed. Fight to get your name in the credits of any game you release. OTOH, many many games never get released.
Hm. Re-reading your post, it occurs to me that the startup may not be a game company.
"Love your work" is often just a way for startups and other small companies to extract unreasonable hours from you, with little payback.
I've done the startup thing. I've worked 9-5 er I mean 9-6, oh, wait it was more like 10-7:30. In the end, any job will require you to put up with things you don't like. Obviously, some jobs are a better fit than others.
One for me, one for my Dad. He's 75, and still writing Mathematica notebooks and software to try to help educate people in developing countries. Rock on dad, this one's for you.
Make sure you do lots of extra-curricular work that you enjoy, and that's difficult. If your grades aren't great, you can show off projects to get jobs. If you want to make your own job, grow it out of your projects.
I failed out of school, and I'm an inconsistent employee at best, but I only know a couple of people who work harder than I do, and they're all business owners.
Not very. Marks anywhere from 40% to 85%. I started when I was fifteen and failed out in my fourth (last) year.
Went back part-time about 5 years later, and failed a compilers course after I decided to forgo the group, write the compiler myself, but got sidetracked leading bots in assault mode on Unreal Tournament.
I really learned how to study about 2 years ago. Sigh.
Spending too much time playing games was a major contributing factor. OTOH I now work in game-development.
I occasionally think about going back so I can some day get a post-grad degree, but don't relish being some profs biatch.
I have a university library-card, read theses and research papers, and generally do whatever I damn well want, while getting paid and hatching product ideas.
