Is it better to work for a multinational gaming company

I am currently looking for a new career opportunity in the iGaming sector and I was wondering if the company culture actually matters for the final product. Does having a diverse team with many different nationalities actually lead to better innovation? What kind of perks should I look for in a top-tier tech employer in this industry? I want to find a place where I can grow professionally and work on products that are used by millions of people globally.
