Offer decent pay.

I know some friends who are full stack, or backend developer, who would like to be game developer, if only the salary match his current position, or at least not lower than 10%>

Pay more salary to attract talent from different sub-major of this software development

it also seems like the games industry as it is now is pretty low pay and high demand working environment. so good luck with that

I had a family friend who worked as a midlevel dev at Rockstar 10 years ago and he was being paid £27k while crunching 100 hour weeks
