A few questions:
- Is this standard practice?
- How can you enjoy your weekend creative activities, and/or, use them for your potential future startups, copyrights, patents, whatever, if you work full-time under such a stringent condition? (can you even write a novel and sell it, while you work full-time as a software engineer? or should you always ask permission first?)
- Is it likely that Carmack had similar obligations while he was at Zenimax? In which case he very carelessly ignored them when he indulged in Oculus work. (but then he also has his rocket hobby going on so I don't know how that panned out in relationship to his employers, Zenimax, or FB).
- This raises an important concern. As a typical employed engineer, we don't pay much attention to the legal repurcussions of our employment. May be we (or I) should not carry out any undertaking without consulting a lawyer (specializing in these matters) first?
