What is the best way to leave?

I look at the experience required on the 'Who is Hiring' threads and sigh -- how am I supposed to get two years' professional experience using a technology that has nothing to do with games, or, how do I pick which tech to invest my time in, given that everything seems to be changing so quickly?

I've moved from games to web development basically by winging it.

If you can code in C++, then becoming competent in JS/PHP/Python/Ruby is a matter of learning their syntax quirks and basics of the standard library. You don't have to worry about the framework-of-the-month churn. These things get popular because they're easy to pick up and well-documented.

Companies recognize that general programming knowledge is the hard part, and happily hire for it. Just avoid recruiters, as they're usually clueless keyword-matchers.

If you're a good developer, and it seems like a lot of people leaving the games industry are, it's not hard. Study up on your Cracking the Coding Interview, HackerRank, Leetcode, and similar stuff, and then just interview for Software Engineer positions. On your resume, list your previous experience as something like "Software Engineer, EA Games, 2016-present" (and include the names of any big games you worked on that people might know and be impressed by).

This is necessary only if you apply to Google and co. Most companies will never ask you to reverse a binary tree. Especially if the company is not in the US.

Apply for a generalist position at a company that doesn’t hire for specific technologies (there are lots and lots of these, basically any of the big famous companies and a lot of smaller ones too).

same, unfortunately ... I loved my time in the game industry, but I also loved spending time (and more money achieved elsewhere) on my family.
